Add fuel sensors

Fuel sensor calibration is crucial to ensure the accuracy of the fuel level readings and to optimize the fleet management system's performance. The software generates reports that accurately depict the fleet's fuel consumption and usage based on readings of the fuel level.

Before you get started

You need to add the number of fuel tanks available per vehicle in the object profile.

  • Login to your account.
  • Go to  Settings > General > Object
  • Double-click on the record for which you want to calibrate the fuel sensor.

To get started 

  • Navigate to Sensor tab.
    Add fuel sensor details tab
    • Activate the analog port connection type by clicking on the checkbox given in the Active column.
    • Click on the dropdown of Connected Sensor and select Fuel Sensor.

    • Click on the Calibration Manage Vehicle Documents btn reminder-1 button. A new window will appear.

To calibrate the fuel sensor

  • Navigate to General
    Ultrasonic fuel sensor calibration tab 2
    • In Sensor Output Unit select the output unit provided by the device from the dropdown list.

Please Note: If you select voltage, liter, gallon, or percentage then the below-given steps will remain the same. 

If you select height then follow the steps given here.

    • Conversion factor: Enter the conversion value as per your device.

A conversion factor is a value used to convert a measurement from one unit to another

    • Tank capacity: Enter the tank's basic capacity in liters.
      • Consider blind area: A blind area in a fuel sensor refers to an area of the tank that is not directly accessible to the fuel level sensor. Click on the checkbox if you wish the software to consider the blind area above and below the fuel level sensors.

      • Top: Enter the area available on the top of the fuel sensor which the sensors cannot detect.

      • Bottom: Enter the area available at the bottom of the fuel sensors which the sensors cannot detect.
    • Fill difference: Enter the minimum value to be considered as fuel fill.

    • Fill detection speed limit: Click on the checkbox. The default speed provided by the system is 15. The system won’t consider fuel fill if the speed is above the given value.
    • Drain difference: Enter the minimum value of fuel to be considered as theft.
    • Drain detection speed: Click on the checkbox. The default speed provided by the system is 15. The system won’t consider fuel drain if the speed is above the given value.
    • Consider stop data: Click on the checkbox if you want to consider the data readings received from the CAN device when the vehicle is at stop.
    • Consider power port:  Click on the checkbox if you want to consider the data readings when the vehicle is connected with a wired sensor in the power port and the vehicle ignition is turned off.
    • Detect drain in motion: Click on the checkbox if you want to consider fuel drain while the vehicle is moving.
    • Consider out-of-range value: Select the checkbox if you want to take into consideration the sensor data that shows significant fluctuations as a result of the sensor's defect.
    • Calibration type: The software provides two types of calibration. Select the type according to your requirement.
      • Automatic: Automatic calibration type will provide the data considering the values fetched from an empty tank, half tank, full tank reading and range.

        • Empty tank reading: Enter the value of the fuel tank when it is empty. 
        • Half tank reading: Enter the value of reading when the fuel tank is half filled.
        • Full tank reading: Enter the value of reading when the fuel tank is full.
          All the values should be added in voltage.
        • Range: Either you can select full tank capacity from the dropdown or you can divide the range as per your requirement. 
      • Manual: Manual calculation can be done in two ways-

        • With algorithm:

          • Data bunch: Enter the time in minutes when you want the average value of raw data to be shown in the graph.
          • Consecutive fill time: The default time provided by the system is 300 seconds. If the fuel is getting filled for minimum 300 seconds then it is considered as fuel fill. 
          • Consecutive drain time: The default time provided by the system is 300 seconds. If the fuel is getting drained for minimum 300 seconds then it is considered as fuel drain. 
          • Ignore initial movement data: The default time provided by the system is 120 seconds. The system will ignore the data for the first 120 seconds and then consider the data provided after this time.
          • Minimum stoppage duration to detect drain: The default time provided by the system is 60 seconds. The system will consider fuel drain if the vehicle is at stop for minimum 60 seconds and the fuel level is going down.
          • Upload file: You can upload the XLS file of fuel showing the conversion of liters in voltage.
            • Download the sample file from the link given, fill in the file, and upload the same. 
        • Without algorithm:

          • Consecutive fill time: The default time provided by the system is 300 seconds. If the fuel is getting filled for minimum 300 seconds then it is considered as fuel fill. 
          • Consecutive drain time: The default time provided by the system is 300 seconds. If the fuel is getting drained for minimum 300 seconds then it is considered as fuel drain. 
          • Ignore initial movement data: The default time provided by the system is 120 seconds. The system will ignore the data for the first 120 seconds and then consider the data provided after this time.
          • Minimum stoppage duration to detect drain: The default time provided by the system is 60 seconds. The system will consider fuel drain if the vehicle is at stop for minimum 60 seconds and the fuel level is going down.
          • Upload file: You can upload the XLS file of fuel showing the conversion of liters in voltage.
            • Download the sample file from the link given, fill in the file, and upload the same. 
        • If you want to connect multiple srnsors,
        • Navigate to Profile.
          Ultrasonic fuel sensor calibration tab
          • In Fuel Tank Select Single or Multiple Tank according to your vehicle.
            If you select multiple tank then you have to add the number of tanks available in the vehicle.
