From Escort Knowledge Base


Definition and purpose of the sensor

мини|304x304пкс|Текущий дизайн ТД-600 High-precision fuel level sensors (FLS, also meters or sensors) of the Escort brand are designed to determine the filling level of petroleum products in fuel tanks, reservoirs and storage tanks. The TD-600 meter (sensor) is used in transport technology as a fuel level meter, in industry - as a level meter for any light petroleum products. Escort FLS measurement type is capacitive. Its readings are based on the dielectric constant of the medium in which it operates; in this case, the medium is various types of light petroleum products (gasoline, diesel, kerosene, motor oil).

More detailed technical characteristics are presented in the тех.паспорте устройства.

Basic terms and concepts

Fuel level sensor (FLS)  - device which is used for measuring fuel level.

Serial number - code consisting of letters and numbers assigned to a device (sensor).

CNT - an oscillatory circuit, thanks to which the basic level of filling of the sensor measuring tubes with fuel is calculated. This level is converted to a final value determined by the data interface.

Data transfer protocol - a set of specific logical-level rules or conventions that govern the exchange of data between different programs or devices. For TD-600, the main transmission protocol is LLS via the RS-485 and RS-232 interfaces.

Режим передачи данных - это своеобразная граница между двумя объектами или узлами, которые регламентируются особым принятым стандартом и реализуются с помощью установленных методов, средств и правил. ТД-600 имеет следующие режимы работы:

  • RS-485 Пассивный по протоколу LLS
  • RS-485 Активный по протоколу LLS
  • RS-232 Пассивный по протоколу LLS
  • RS-232 Активный протоколу LLS и ASCII
  • Аналоговый
  • Частотный

Интерфейс - физический способ подключения и/или набор программных инструментов, с помощью которого осуществляется передача данных между двумя или более устройствами.

RS-485 Пассивный- цифровой режим передачи данных. Датчик ждет соответствующего запроса от принимающего устройства. Работает по протоколу LLS. На основе CNT формируется значение в условных единицах выбранного диапазона (1-1023 у.е. или 1-4095 у.е.). На датчиках с серийным номером выше 26339 RS-485 и RS-232 работают паралельно.

Преобразователь - цифровой преобразователь RS-485 в USB (С200М или С200М2) для настройки проводных датчиков.

Активный (периодический) RS-485 - разновидность вышеуказанного режима работы, при котором датчик, не ожидая запроса от приемника, сам передает пакеты с данными каждые 2 секунды.

RS-232 - цифровой режим передачи данных. Работает по протоколу LLS и ASCII, при наличии запроса LLS датчик отвечает по протоколу LLS при отсутвии запроса датчик активно выдает данные в формате ASCII. На основе CNT формируется значение в условных единицах выбранного диапазона (1-1023 у.е. или 1-4095 у.е.). На датчиках с серийным номером выше 26339 RS-485 и RS-232 работают паралельно.

Аналоговый - режим, при котором на основе CNT формируется соответствующий вольтаж в примерном диапазоне 0,2-5В.

Частотный - режим, в котором на основе CNT формируется соответствующая частота в Гц (301-1323 Гц при диапазоне значений 1-1023; 301-4395 Гц при диапазоне значений 1-4095).

Импульсный - режим, в котором на основе CNT формируется пачка импульсов частотой 27 Гц. Количество импульсов в пачке соответствует измеренному уровню топлива. Минимальному уровню соответствует пачка из 2 импульсов, максимальному - пачка из 1025 импульсов.

Навигационный терминал -  это главный элемент системы мониторинга работы транспорта, осуществляемого с помощью спутниковой связи. Без него невозможно осуществлять контроль транспорта, определить координаты местонахождения транспортного средства. Он собирает информацию с датчиков и бортовой системы транспорта, а затем осуществляет её передачу на устройство\сервер, которые принадлежат контролирующему процесс специалисту.

Preparation

Preparing the Tank

To prepare the tank you should:

Why should the sensor be mounted in the geometric center of the tank?

The highest point must be chosen so that the sensor can measure the level of all the fuel inside the tank without any blind spots.

The fuel level readings from a sensor installed in the center of the tank will be least affected by movement and fuel overflow in the tank.

If it is not possible to install the sensor in the center of the tank, consider installing two sensors diagonally at two corners. When fuel flows to one side of the tank, the level on the corresponding sensor will rise, and on the opposite side, the level will correspondingly decrease, while the average level will remain unchanged.

Видео пример важности установки датчика по геометрическому центру бака. без|мини|805x805px|Положение датчика и перетекание топлива

Attention: Before starting the calibration, the vehicle/fuel tank must be positioned flat in relation to the horizon, i.e. on a level surface without a slope.

If the tank has an irregular geometric shape, the sensor must be installed at the maximum depth of the tank, closer to the geometric center.

без|мини|737x737пкс|Датчик установлен в самое высокое место бака

When installation in the center is impossible - two or more FLS.

To increase accuracy and reduce level fluctuations, install two sensors in one tank. This solution is mainly used in tanks with a capacity of more than 600 liters and having a length of 1500 mm. Sensors must not be installed close to the walls of the tank.

Also, two or more sensors should be installed if it is not possible to install the sensor in the center of the tank and (or) the tank has an elongated shape, i.e. The length of the tank is significantly greater than its height. без|мини|748x748пкс|Два датчика установленных по диагонали Note. Installing a single sensor in an elongated tank will allow you to detect drains and refills. But increased level fluctuations while driving may not allow the monitoring platform to correctly read fuel consumption. Therefore, installing two sensors is preferable.

Preparing the sensor

Preparing the sensor tubes

Before calibrating the sensor, you should determine the future length of the measuring tubes in accordance with the height of the tank and cut or extend them. The length of the tubes should be calculated according to the following formula:

L = H - 15 mm,

where L - tubes length after changing the length

and

H - height of the tank at the installation point.

ATTENTION!!! The minimum length of the tubes should not be less than 15 cm (150 mm). Otherwise, it will most likely not be possible to obtain adequate graphics. The maximum length of the tubes can reach 6m.

без|мини|843x843пкс|Измерение высоты бака без|мини|846x846пкс|Измерение длины трубок Use a hacksaw to cut the tubes. When sawing, be careful not to damage the connection of the tubes to the circuit board inside the sensor head and to prevent metal shavings from falling into the tubes. без|мини|Обрезка трубок|600x600пкс Avoid getting shavings inside the tubes - this may lead to a short circuit in the sensor; if this happens, blow the tubes with compressed air through the drainage holes under the sensor flange.

Connect the sensor to the USB-RS-485 converter using a 6-pin MOLEX connector or using cable clamps if a cable route is connected to the sensor. Orange wire is line A of the RS-485 sensor interface, white wire is line B of the RS-485 sensor interface, black wire is GND, red is PWR. без|мини|800x800пкс|Датчик подключенный при помощи MOLEX без|мини|800x800пкс|Датчик подключенный при помощи кабель-трассы (укороченной) и кабельных зажимов We recommend using our Escort C200M/C200M2 USB-RS-485 converter, since we cannot guarantee 100% compatibility of our devices with converters from other brands.

When working with a laptop, we recommend connecting it to the power supply and/or connecting an additional USB cable to the ADD connector of the PWR C200M. Otherwise, there may not be enough power to operate the sensor and transmitter.

Along with installing the configurator 1.0.2.38, the drivers for the C200M will be installed automatically.

If you use C200M2 on Windows 10 and 11 operating systems, drivers should be installed automatically from Windows Update, on the Windows 7 operating system and below, you may need to disable the electronic signature of drivers and manually install drivers for the С200M2.

If the driver was installed correctly, then after connecting the converter to your PC/laptop, you will see the STMicroelectronics Virtual COM Port (1)(C200M) or USB-SERIAL CH341A (2)(C200M2) device in the COM and LPT ports section of the Windows device manager " to enter this menu, press win+r and enter devmgmt.msc and press OK (3) and then expand the com ports submenu (4)"

The com port number displayed in this menu is also needed to connect the sensor.

Sensor calibration

Файл:Калибровка ТД-600 в конфигураторе 2.7.1.gif

After you have lengthened or shortened the sensor tubes - you must perform a sensor calibration procedure.

To do this you need:

  • Insert the centralizer into the tubes
  • Fill the tubes with fuel (by covering the drain holes with duct tape and filling the tubes by turning the sensor upside down or immersing the sensor tubes completely in fuel)
  • Wait for CNT level to stabilize (1)
  • Click “Set Current level” (2) opposite “Full”
  • The value “Full”(3) should change to a value close to the current CNT value (1), but not equal to it, because this value is set according to the temperature compensation of the sensor

857x857пкс без|мини|671x671пкс|Центратор без|мини|670x670пкс|Центратор на трубках

  • Empty the tubes of fuel, leave the centralizer in the tubes
  • Wait for CNT to stabilize (1)
  • Click “Set Current level” (2) opposite “Empty”
  • The value "Empty" (3) should change to a value close to the value of the current CNT (1), but not equal to it, since this value is set according to the temperature compensation of the sensor

840x840пкс

  • The sensor level should display as 1, the sensor calibration process is complete.

Thus, CNT should increase as the sensor tubes fill with fuel. It should change from a value close to the Empty calibration value to the Full calibration value.

Setting the calibration value Full and Empty manually

We do not recommend using this functionality, but you can set the Full and Empty calibration values manually to save time when you are using sensors of the same length in the same tanks.

Attention!!! Setting calibration values manually will most likely increase the sensor error! We do not recommend doing this!

To do this, enter the calibration values Full and Empty of the previously calibrated sensor into the corresponding fields in the configurator and click “Set” against “Empty” and “Full”

Setting the mode, range and network address

Setting the mode

Under Modes (1), you can switch between the sensor's operating modes. The mode name is the same as the interface used to physically connect the sensor to the GPS terminal.

Check the desired mode and press Set (2).

825x825пкс

- Режим RS-485 (RS485 mode) следует выбрать, когда планируется подключать к линии А и В интерфейса RS-485 терминала. Терминал должен иметь функцию опроса датчиков, например запрашивать у них информацию. Терминал должен уметь опрашивать датчики в соответствии с протоколом LLS. На датчиках с серийным номером выше 26339 RS-485 и RS-232 работают паралельно.

- Аналоговый режим (Analog mode) используется при подключении датчика к аналоговому входу терминала (AIN),  который может принимать сигнал от датчика в диапазоне ≈0.2В … ≈9.0 В

- Частотный режим (Frequency mode) используется при подключении к GPS терминалу к входам, которые могут принимать и считывать сигналы в диапазоне 300 Hz … 1323 Hz  или 300 Hz … 4395 Hz

- Периодический/импульсный режим (Periodic/impulse mode) (Periodic/Active RS485 mode) следует использовать при подключении датчика к импульсному входу терминала.

- Периодический/активный режим (Periodic/Active RS485 mode) следует использовать, если терминал имеет интерфейс подключения RS-485, но не может самостоятельно опрашивать датчик, например запрашивать у него информацию; датчик будет отправлять свои показания самостоятельно каждые 2 секунды.

- Режим RS-232 (RS-232 mode) следует выбирать, если подключение осуществляется по интерфейсу RS-232 (входы Rx и Tx); На датчиках с серийным номером выше 26339 RS-485 и RS-232 работают паралельно.

in this mode, the sensor waits for a request from the terminal via the LLS protocol, e.g:

  • 3101066C это запрос информации об уровне топлива и температуры датчика с сетевым номером 1 (ID датчика в режиме RS-232);
  • 3E0106110100010030 ответ от датчика на запрос указанный выше; 11 – температура HEX (17°C), 01 00 – уровень 00 01 HEX (обратный порядок байтов, 1501 это 0115 означет уровень 276); остальные байты не информативны, за исключением последнего, который является контрольной суммой CRC-8 MAXIM;
  • Если на датчик не поступало таких запросов в течении 10 сек, то он начинает отправлять свои показания в формате ASCII, например F=С0F2 t=11 N=0001.0 <CR><LF>) F это CNT, t это темпераутра, N это уровень, все в формате HEX.

865x865пкс

Setting the range

If you are configuring the sensor to operate in RS-485, RS-232, Active RS-485 or Frequency modes, you can select a range of 1-1023 or 1-4095 (1) . In frequency mode, the range will be 300Hz to 1323Hz or 300Hz to 4395Hz.

After changing the range, press “Set” (2).

860x860пкс

The range 1-1023 is most often used for sensors that are shorter than 1 meter. However, if it is a stationary tank with a small height, while the length and width are greater than 2-3 meters, it is better to choose the range 1-4095.

Setting the network address

The default network address of the sensor is 1; if more than one unit is installed or other LLS devices are added, the network address on the sensor may need to be changed. The network address of each sensor must also be specified in the settings of the receiving device (navigation terminal).

Attention!!! There cannot be two devices with the same network address on the same line; this will cause a conflict.

To change the network address, enter a new address in the range of 0-255, click “Change Network Address” (1), enter the new address (2), click “OK”(3), then you need to “Search for Sensors”(4), to connect to the sensor with the new address.

Master mode

The TD-600 sensor also has an additional master mode in which the TD-600 polls up to 7 connected sensors (slaves) via RS-485 using the LLS protocol and transmits its and their data in ASCII format in the active mode via RS-232

Example of information output by a sensor with 2 connected slaves:

t_0=11;N_0=0001.0;t_1=15;N_1=02D8.0;t_2=FFFFFFBF;N_2=0025.0

где t_* это температура в HEX

11 это 17°C, 15 это 21°C, FFFFFFBF это отрицательное значение, первые 6 знаков можно игнорировать BF это 191 тоесть значение -65°C по формуле x-256.

N_* уровень в HEX

0001 это 1, 02D8 это 728, 0025 это 37

Цифра после номера означает номер слейва, 0 это данные самого ТД-600, 1-7 это номера слейвов.

Для включения режима мастера установите галочку на режиме Master mode и нажмите Установить

Angle measurement

Sometimes monitoring platforms may detect false drains and refueling while the vehicle is moving.

To solve this problem, you can use readings of the accelerometer built into the TD-600 sensor.

For this purpose, select RS-485 only (this function will not work in Periodic RS-485 mode or in any other mode) The main network address of the sensor must be different from 255.

Check the 'Angle' box (1) in the Modes section of the configurator. Then, click Set (2) first and then Search for sensors.

In this mode the tilt angle will be transmitted to the next from the main address of the sensor.

Press Horizon (3) to calibrate the tilt zero.

Tank calibration

Once the length sensor has been adjusted to the height of the tank and the sensor has been calibrated, you need to install it in the tank.

Install the sensor into the tank of the installed tube in the previously drilled hole ø 30-35 mm. Make sure the gasket is installed between the sensor and the tank. After this, screw the screws from the installation kit into the previously drilled ø 3mm holes.

Proceed to tank calibration. This procedure will result in a "level-liters" (or "level-gallons") table that will allow your monitoring platform to convert the level values that the sensor provides into liters/gallons that are displayed in the monitoring platform reports.

In order to create such a table, you need to fill the tank by step by step adding fuel to the tank batch by batch and recording level-liter(/gallon) pairs after each batch using the Tare menu in the application.

Suppose you need to tare a 100L tank in ten 10L portions.

To do this you should:

  • Connect sensor Make sure that the filtration is set to “No” (1). Filtration slows down the level calculation and can increase the tank calibration time. Create an Excel table. Save it in .csv format. The first row of the table should look like this: Файл:Первая строчка тарировки в Excel.png You can also create a text file on your PC/Phone or manually record calibration
  • Select whether calibration is performed by filling or draining. The Filling method is recommended as it is more accurate. If you select the Drain method, you cannot be sure what exact amount of fuel is in the tank and whether the tank is full or not.
  • Select portion size

ATTENTION! Portion volume is not the number of portions! This is the number of liters/gallons in each portion! In the example below, the tank supposedly contains 100 liters and this volume can be divided into 10 portions of 10 liters. If the volume of the tank was 300L and it needed to be divided into 10 portions, the portion size would be 30L.

  • Start calibrating the tank by pouring portions into the tank or emptying the tank for a given portion and recording the level in the table after it has stabilized

An example of calibration by filling in portions of 10 liters and imagine that in this case there are 10 liters in the tank that cannot be removed and when the sensor is placed in the tank it immediately shows the value 115 instead of 1.

Файл:Тарировочная таблица, уровень 115, 10 литров.png421x421пкс

You add the first portion of fuel to the tank. The level should change from 115 to some other value. If the level does not change, check the sensor drain holes. They may be blocked by electrical tape, which must be removed after the sensor has been calibrated. If the holes are blocked, the air inside the tubes will prevent fuel from getting inside the tubes.

Файл:Добавление второй порции в бак.png

Next, add the following row to your table.

Файл:Тарировочная таблица, уровень 223, 20 литров.png

Continue this until the tank is full.

However, if there are bends or other irregularities in the shape of the tank, the volume of fuel portions should be reduced until the fuel level is above the irregularly shaped section of the tank.   After overcoming such a section, you should return to the original portion volume.

Assume that you do the tank calibration in portions of 10 liters as before. The level rises to an area with a complex shape.

660x660px

You reduce the serving size from 10 to 5 liters. And continue adding portions until you overcome the area with a complex shape.

664x664пкс

When the level is above the problem area, you can return to the original serving volume of 10 liters.

Once the tank is full, you will have a calibration chart like the following example.

401x401пксФайл:Законченная таблица тарировки.png

If in your case the level does not reach 1023 or 4095 because the tank cannot be filled completely, do not worry about it. It is acceptable that your table would end up like the following example, even though the sensor range is 1-1023. без|мини|Таблица для бака, который нельзя заполнить на 100%|511x511пкс The number of servings depends on the capacity of the tank. See the table with our recommendations below.

Recommended number and portion size for calibrating the tank
Tank volume Number of portions Volume of each portion

(Tank Volume / Number of portions)

0-60 10-20 3-4
61-100 12-20 5
101-500 10-50 10
501-1000 20-50 20
Over 1000 As per your capabilities. The rule of thumb is that the larger the portions and smaller the volume, the more accurate the data will be

The rule of thumb: more portions means more accurate reports on the monitoring platform.

You can create a table on your platform by loading it from a file or by entering values manually. без|мини|687x687пкс|Загрузка таблицы на Wialon (пример). Не забудьте отметить "Генерировать пары XY"

Tilted tank calibration with 2 FLSs

If it is not possible to level the car/tank with respect to the horizon, you can calibrate it in the tilted position of the tank.

Technically, this kind of calibration is no different from the usual one: you pour a portion of fuel into the tank, wait for the level to stabilize, fix it, and fill in the next portion.

However, the details of such calibration are much more important, so the algorithm of actions should be as follows:

  1. Pour portions of fuel into the tank until the fuel level reaches the measuring tubes of the second FLS, which is located higher due to the inclination.
  2. When the second sensor reaches the fuel level, reduce the size of the poured portion by half. IMPORTANT: it is necessary to reduce the portion only in the calibration tables for both FLS; the actual volume of the portion being filled remains unchanged.
  3. Once the tubes of the sensor located lower down are completely immersed in fuel, the calibration of this FLS is considered complete.
  4. However, before continuing calibration of the second FLS, it is necessary to return the nominal portion volume to the original (i.e. double it). IMPORTANT: The actual portion size still remains unchanged until the tank is finally filled and the calibration process is completed.

Thus, the resulting calculation tables (calibration tables) will be adequately accepted by the monitoring platform if a third FLS (virtual) is created in it, which is the sum of two real FLS. без|мини|517x517пкс|Пример тарировочной таблицы ДУТ1 без|мини|450x450пкс|Пример тарировочной таблицы ДУТ2

Calibration of a tank whose height varies along its length

This method of calibration is in many ways similar to that presented in the previous part.

The algorithm of actions is as follows:

  1. Pour portions of fuel into the tank until the fuel level reaches the measuring tubes of the second FLS, which is located higher due to the difference in height.
  2. When the second sensor reaches the fuel level, reduce the size of the poured portion by half. IMPORTANT: it is necessary to reduce the portion only in the calibration tables for both FLS; the actual volume of the portion being filled remains unchanged.
  3. Continue calibrating in this manner until the tank is full.

    Thus, the resulting calculation tables (calibration tables) will be adequately accepted by the monitoring platform if a third FLS (virtual) is created in it, which is the sum of two real FLS. без|мини|632x632пкс|Пример тарировочной таблицы ДУТ 1 без|мини|Пример тарировочной таблицы ДУТ 2

Filtration

Once the tank calibration is complete, select the desired filtration degree (1) and press “Set mode” (2)

839x839пкс

Below are recommendations for choosing the filtration level for different types of vehicles:

Recommended filtration level for wired FLS

0-1 Stationary units
2-6 Vehicles on high or medium quality roads
7-12 Agricultural machinery units
13-15 Heavy-duty machinery

General tips for installing filtration:

  • If the length of the tubes is less than 30 cm, the filtration level must be set higher than usual
  • The closer the sensor is to the tank walls, the higher the filtration is
  • The worse the road surface, the higher the filtration
  • You only need to set the median filter type

Sensor calibration

After you have lengthened or shortened the sensor tubes, you need to carry out the sensor calibration procedure.

To do this you need:

  • Go to the "Settings" menu

995x995px

  • Insert the centralizer into the tubes
  • Fill the tubes with fuel (by sealing the drain holes with duct tape and filling the tubes, turning the sensor upside down, or submerging the sensor tubes completely in fuel)
  • Wait for the CNT level to stabilize (2)
  • Deselect the "Calibration without fuel" slider (1)
  • Press "Full" (3)
  • The value "Full" (4) should change to a value close to the value of the current CNT (2), but not equal to it, since this value is set according to the temperature compensation of the sensor

990x990пкс без|мини|671x671пкс|Центратор без|мини|670x670пкс|Центратор на трубках

  • Empty the tubes of fuel, leave the centralizer in the tubes
  • Wait for CNT to stabilize (2)
  • Click "Empty" (3)
  • The value "Empty" (4) should change to a value close to the value of the current CNT (2), but not equal to it, since this value is set according to the temperature compensation of the sensor

977x977px

Thus, CNT should increase as the sensor tubes fill with fuel. It should change from a value close to the Empty calibration value to the Full calibration value.

854x854пкс

ATTENTION! UNLOCK THE DRAINAGE HOLES AFTER CALIBRATION!!!

726x726пкс

Calibration without fuel

An alternative calibration option is calibration without fuel.

In this case, make sure that the sensor tubes are empty, there is no fuel in them, but the centralizer must be inserted into the tubes. Leave the "Calibrate without fuel" switch (1) active (green) and press "Calibrate" (2) . The values ​​above the Empty and Full buttons will change automatically.

973x973пкс

If you calibrate the sensor without fuel, the operating range may change slightly.

Initially there are two measurement ranges:

  • From 1 to 1023
  • From 1 to 4095

The sensor never sends a value of 0. If there is no fuel, level 1 is displayed.

When calibrating without fuel, since the sensor does not know what fuel will be used, the "Empty" value is set based on the current (CNT), the "Full" value is set by a formula and, depending on the length of the tubes and the final fuel used, the range may change .

For example, when the tank is full, the sensor will show 3843 instead of 4095, or it is possible that when the tank is 98% full, the sensor will already display the value 4095.

We recommend, if possible, calibration with fuel.

- Режим RS-485 (RS485 mode) следует выбрать, когда планируется подключать к линии А и В интерфейса RS-485 терминала. Терминал должен иметь функцию опроса датчиков, например запрашивать у них информацию. Терминал должен уметь опрашивать датчики в соответствии с протоколом LLS. На датчиках с серийным номером выше 26339 RS-485 и RS-232 работают паралельно.

- Аналоговый режим (Analog mode) используется при подключении датчика к аналоговому входу терминала (AIN),  который может принимать сигнал от датчика в диапазоне ≈0.2В … ≈9.0 В

- Частотный режим (Frequency mode) используется при подключении к GPS терминалу к входам, которые могут принимать и считывать сигналы в диапазоне 300 Hz … 1323 Hz  или 300 Hz … 4395 Hz

- Периодический/импульсный режим (Periodic/impulse mode) (Periodic/Active RS485 mode) следует использовать при подключении датчика к импульсному входу терминала.

- Периодический/активный режим (Periodic/Active RS485 mode) следует использовать, если терминал имеет интерфейс подключения RS-485, но не может самостоятельно опрашивать датчик, например запрашивать у него информацию; датчик будет отправлять свои показания самостоятельно каждые 2 секунды.

- Режим RS-232 (RS-232 mode) следует выбирать, если подключение осуществляется по интерфейсу RS-232 (входы Rx и Tx); На датчиках с серийным номером выше 26339 RS-485 и RS-232 работают паралельно.

в этом режиме датчик ждет запроса от терминала по протоколу LLS, например:

  • 3101066C это запрос информации об уровне топлива и температуры датчика с сетевым номером 1 (ID датчика в режиме RS-232);
  • 3E0106110100010030 ответ от датчика на запрос указанный выше; 11 – температура HEX (17°C), 01 00 – уровень 00 01 HEX (обратный порядок байтов, 1501 это 0115 означет уровень 276); остальные байты не информативны, за исключением последнего, который является контрольной суммой CRC-8 MAXIM;
  • Если на датчик не поступало таких запросов в течении 10 сек, то он начинает отправлять свои показания в формате ASCII, например F=С0F2 t=11 N=0001.0 <CR><LF>) F это CNT, t это темпераутра, N это уровень, все в формате HEX.

Setting the range

If you are configuring the sensor to operate in RS-485, Active RS-485, or Frequency modes, you can select the range 1-1023 or 1-4095 (1) . In frequency mode, the range will be from 300Hz to 1323Hz or 300Hz to 4395Hz.

After changing the range, press “Set parameters” (2).

605x605пкс

979x979пкс

The range 1-1023 is most often used for sensors that are shorter than 1 meter. However, if we are talking about a stationary tank, the height of which is small, then the length and width are more than 2-3 m, it is better to choose the range 1-4095.

Setting the network address

The default network address of the sensor is 1; if more than one unit is installed or other LLS devices are added, the network address on the sensor may need to be changed. The network address of each sensor must also be specified in the settings of the receiving device (navigation terminal).

Attention!!! There cannot be two devices with the same network address on the same line; this will cause a conflict.

To change the network address, enter a new address in the range 0-255 in the “Network address” field (1) and click “Set parameters” (2)

Tank calibration

Once the length sensor has been adjusted to the height of the tank and the sensor has been calibrated, you need to install it in the tank.

Install the sensor into the tank of the installed tube in the previously drilled hole ø 30-35 mm. Make sure the gasket is installed between the sensor and the tank. After this, screw the screws from the installation kit into the previously drilled ø 3mm holes.

Proceed to tank calibration. This procedure will result in a "level-liters" (or "level-gallons") table that will allow your monitoring platform to convert the level values that the sensor provides into liters/gallons that are displayed in the monitoring platform reports.

In order to create such a table, you need to fill the tank by step by step adding fuel to the tank batch by batch and recording level-liter(/gallon) pairs after each batch using the Tare menu in the application.

Suppose you need to tare a 100L tank in ten 10L portions.

To do this, you should connect the sensor and go to settings and check that the filtering is set to 0.

Filtration slows down level calculations and can increase tank calibration time.

Then go to the tank calibration menu

1025x1025пкс


Then, you can click Start to create a new table, or click Resume to select an existing table from your smartphone memory and continue working with it. If you click Resume, you will need to locate the table file on your Android device that you created/downloaded earlier. Select another folder using the Main Menu button (1) or using the drop-down menu (2). Select the table and click on it (3)

If you click Start, you will also need to select the folder in which the table will be saved (2) and click the button to select it (3)

без|мини|752x752px|Выбор папки и создание нового файла тарировки Then, you can select the Fill or Drain method (1, 2). The Fill method is recommended as it is more accurate.

If you select the Drain method, you cannot be sure what exact amount of fuel is in the tank and whether the tank is full or not.

Next, give the table file a name (3) and set the portion size (4).

ATTENTION! Serving volume is not the number of servings! This is the number of liters/gallons in each serving! In the example below, the tank supposedly contains 100 liters and this volume can be divided into 10 portions of 10 liters. If the volume of the tank was 300L and it needed to be packaged into 10 servings, the serving size would be 30 L.

After this, click Continue (5).

After this, you will have a table in which the first row will be 0 liters and level 1.

You can always pause tank calibration and resume it.

The table is saved automatically after you click the + button.

Next, you should add the first portion of fuel to the tank. Once the level changes (3)  and is displayed as Stable (4), press the + button (1).

In this example, level (3) does not change because during the work on this manual we did not have fuel to carry out a real calibration of the tank. In your case, the level should change (if the fuel touches the tubes) and be Stable before you press the + button.

The following line (2) will appear. The value in the Fuel column will increase according to the Step size (5) you specified when you created the table or when you last modified it (3).

You can also change any line by pressing and holding it for some time, after which a dialog box will appear. This way you can correct possible errors.

без|мини|464x464px|Редактирование строки тарировки If you press a line and hold it and swipe left, it will be deleted.

Файл:Удаление_строки_тарировки.gif

Then, add the next portion of fuel to the tank. Wait for the level to change and stabilize, then press the + button (1). Continue this until the tank is full.

What to do if it is not possible to completely empty the tank?

If you cannot completely empty the tank, you should somehow calculate the amount of fuel that is in the tank. After this, you can manually edit the table so that it looks like the example below. Or simply edit the table file before you upload it to the monitoring platform.

Let's assume that there are already 10 liters of fuel in the tank that cannot be removed, so when you place the sensor in the tank, it will immediately begin to show the level of 115, instead of 1.

Next, you can add the next portion to the tank. The level value should change. If the level does not change, check the drain holes. They may be blocked by duct tape that you may have used while calibrating the sensor or by pieces of sealing compound.

If this happens, the air trapped inside the tubes prevents the fuel from rising. без|мини|689x689px|Загрузка таблицы на Wialon (пример). Не забудьте отметить "Генерировать пары XY"

Tilted tank calibration with 2 FLSs

If it is not possible to level the car/tank with respect to the horizon, you can calibrate it in the tilted position of the tank.

Technically, this kind of calibration is no different from the usual one: you pour a portion of fuel into the tank, wait for the level to stabilize, fix it, and fill in the next portion.

However, the details of such calibration are much more important, so the algorithm of actions should be as follows:

  1. Pour portions of fuel into the tank until the fuel level reaches the measuring tubes of the second FLS, which is located higher due to the inclination.
  2. When the second sensor reaches the fuel level, reduce the size of the poured portion by half. IMPORTANT: it is necessary to reduce the portion only in the calibration tables for both FLS; the actual volume of the portion being filled remains unchanged.
  3. Once the tubes of the sensor located lower down are completely immersed in fuel, the calibration of this FLS is considered complete.
  4. However, before continuing calibration of the second FLS, it is necessary to return the nominal portion volume to the original (i.e. double it). IMPORTANT: The actual portion size still remains unchanged until the tank is finally filled and the calibration process is completed.

Thus, the resulting calculation tables (calibration tables) will be adequately accepted by the monitoring platform if a third FLS (virtual) is created in it, which is the sum of two real FLS. без|мини|517x517пкс|Пример тарировочной таблицы ДУТ1 без|мини|450x450пкс|Пример тарировочной таблицы ДУТ2

Calibration of a tank whose height varies along its length

This method of calibration is in many ways similar to that presented in the previous part.

The algorithm of actions is as follows:

  1. Pour portions of fuel into the tank until the fuel level reaches the measuring tubes of the second FLS, which is located higher due to the difference in height.
  2. When the second sensor reaches the fuel level, reduce the size of the poured portion by half. IMPORTANT: it is necessary to reduce the portion only in the calibration tables for both FLS; the actual volume of the portion being filled remains unchanged.
  3. Continue calibrating in this manner until the tank is full.

    Thus, the resulting calculation tables (calibration tables) will be adequately accepted by the monitoring platform if a third FLS (virtual) is created in it, which is the sum of two real FLS. без|мини|632x632пкс|Пример тарировочной таблицы ДУТ 1 без|мини|Пример тарировочной таблицы ДУТ 2

Filtration

After tank calibration is completed, select the required “Filtration” (1) and click “Set parameters” (2)

965x965пкс

Below are recommendations for choosing the filtration level for different types of vehicles:

Recommended filtration level for wired FLS

0-1 Stationary units
2-6 Vehicles on high or medium quality roads
7-12 Agricultural machinery units
13-15 Heavy-duty machinery

General tips for installing filtration:

  • If the length of the tubes is less than 30 cm, the filtration level must be set higher than usual
  • The closer the sensor is to the tank walls, the higher the filtration is
  • The worse the road surface, the higher the filtration
  • Only median filtering type should be set

Common problems and solutions

Level 7000

Level 7000 is an error code Short circuit. This indicates that there is dirt, water, chips or other impurities in the tubes. All of these can be highly conductive, while the sensor is designed to work with dielectrics such as fuel.

You should clean the sensor tubes - preferably by blowing them through the drain holes with compressed air.

If this error occurred after the start of operation of the sensor, it means that most likely these impurities got into the sensor tubes from the tank and in this case it is also necessary to flush the tank.

Level 6500

This code may indicate that the tubes have lost contact. This error code may be generated immediately after cutting the tubes. In this case, simply calibrate the sensor.

If this does not help, check the CNT. If the CNT is below 10,000, it is very likely that the tubes are not in contact with the sensor board.

Take a photo of the sensor head (the sensor serial number should be visible), its tubes (the correspondence or discrepancy of the tubes length should be clearly visible), take a screenshot of the main screen of the sensor and the Settings menu page in the application and send these data to tech support.

The sensor does not connect or is not recognized in the application

If the sensor does not connect to the configurator, do the following:

  • Make sure that the correct COM port number is selected and that drivers and libraries are installed (STMicroelectronics Virtual COM Port (1)(C200M) or USB-SERIAL CH341A (2)(C200M2) in the COM and LPT ports section of the Windows device manager "to enter this menu, press win+r and enter devmgmt.msc and press OK (3) and then expand the com ports submenu (4)" 877x877пкс Файл:Выбор ком порта и ДУТ.png
  • If possible, connect another sensor that is sure to work; if it connects, then there are no problems with the COM port or converter
  • Connect another USB cable to the C200M (ADD PWR connector); check if the USB cable is working
  • If another converter is used, ensure that sufficient power is supplied to the sensor (12 volts is optimal)
  • When connecting the sensor, press Search for sensors within 15 seconds after power is applied to the sensor
  • If the above does not help, reflash the FW of the sensor
  • If you cannot complete the firmware, contact our technical support

Checking the connection between the sensor and the terminal via RS-485

If the sensor, for some reason, after you have configured everything correctly, does not transmit data to the terminal, you need to find out whether data is being exchanged between devices.

To do this, connect the sensor to the terminal via RS-485. Connect power to both devices.

After that, take the RS-485-USB converter and connect it between the sensor and the terminal as shown below:

For RS-485, lines A and B of the converter must be connected to lines A and B of the sensor без|мини|820x820пкс|Подключения для снятие лога RS-485 Запустите terminal.exe и настройте СОМ порт как показано ниже:

Baud rate – 19200, Parity – None, Stop-bits – 1, Handshaking – None

Also, check HEX or ASCII depending on the format in which information from the sensor will be transmitted. For all sensors except the TD-600 configured in RS-232 mode, you must select HEX.

After connecting the converter correctly, select the COM port and click Connect. If the sensor is polled by the terminal and responds, then everything is in order. без|мини|667x667пкс|Датчик отвечает терминалу по RS-485 If there is no communication between the two devices, try polling the sensor manually.
