Calibrate Fuel Sensor

The system empowers users to configure fuel sensors on their vehicles and establish precise calibration settings for these sensors. This process is essential for achieving accurate fuel level readings, thereby enhancing the overall efficiency and performance of the fleet. 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.

• Log in 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 the Sensors tab.
  
  
  • Activate the analog or digital 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 button. A new window will appear.
    

To Calibrate the Fuel Sensor

• In the Sensor Output Unit section, kindly choose the appropriate output unit provided by the device for the fuel sensor value from the dropdown list.

• Conversion factor: Enter the conversion value based on your device's output unit.

• Tank Capacity: Enter the tank's basic capacity in liters.
• Consider Blind Area: A blind area in a fuel sensor is defined as the portion of the tank that is not reachable by the fuel level sensor. To ensure that the software accurately considers the blind area both above and below the fuel level sensors, please select the appropriate checkbox.

• • Top: Please specify the area at the top of the fuel sensor that remains undetectable by the sensors.
  • Bottom: Please specify the area at the bottom of the fuel sensors that remains undetectable by the sensors.

• Select Tank Type from the dropdown list to choose the shape of the tank for which you are performing calibration.
  
• Choose the appropriate Tank Material from the dropdown list to specify the material from which the tank is constructed.
• Depending on the chosen tank material, you will need to select the appropriate Sensor Mounting option, which relates to the installation position of the sensor.
• Please specify the length of the sensor as configured within the tank in the Sensor Length field.
• Fill Difference: Set the threshold value for fuel refills. If the fuel level increases beyond this value, the system will consider that data to recognize a Refill event and trigger an alert. This field will also help to eliminate false refill events by allowing you to adjust the fill difference value in response to fluctuating data.
• Drain Difference: Set the threshold value for fuel pilferage. If the fuel decrease goes below this value, the system will consider that data to recognize a Drain event and send an alert. This field will also help to eliminate false drain events by allowing you to adjust the drain difference value in response to fluctuating data.
  

• Sensor Angle: To specify the installation angle of the sensor, please check the corresponding box and enter the degree at which the sensor has been installed.
• Consider Stop Data: By enabling this option, the system will consider the data collected while the vehicle is in stop condition in its calculations.
• Consider Power Port: Enabling this option allows users to avoid false fill and drain events triggered by voltage drops caused by the connection or disconnection of the main power port.
• Detect Drain in Motion: To detect and consider the drain event while the vehicle is in motion, select the corresponding checkbox.

• Consider out-of-range value: To consider fuel values that are outside the defined calibration range, please check the corresponding checkbox.
  For instance, if the calibration range is established between 0.5V and 5V, and the device reports a value of 5.2V, it is necessary to enable this option in order to include that value in the system's calculations.

• Calibration type: The software provides two calibration options. Choose the method that best meets your specific needs.
  • Automatic: The automatic calibration method gathers data based on readings taken from an empty tank, a half tank, a full tank, and the specified range to show the fuel level on the platform.
    

• • • Empty tank reading: Enter the voltage reading recorded when the fuel tank is empty.
    • Half tank reading: Enter the reading value recorded when the fuel tank is half full.
    • Full tank reading: Enter the reading value recorded when the fuel tank is full.
    • Range: Either you can select full tank capacity from the dropdown, or you can divide the range as per your requirement. 

• • Manual: Manual Calibration uses data from the calibration range, with corresponding voltages and liters recorded in an Excel sheet. The system then applies a predefined algorithm to accurately calculate and display the fuel level, enhancing accuracy.
    
    
    • Download the sample file using the link provided. Once you have the file, fill in the corresponding voltage readings next to their respective liter values, and then proceed to upload the completed file from Upload File option.

• Consecutive Fill Duration refers to the continuous time interval during which the fuel level increases steadily without interruption. This duration is used to identify and confirm a fuel refill event.
• Consecutive Drain Duration refers to the continuous time interval during which the fuel level decreases steadily without interruption. This duration is used to identify and confirm a fuel drain event.
• Data Filtration Level: In this field, users can select the amount of data to process in a single batch. The system divides the incoming data into multiple batches to smooth the graph and minimize fluctuations. It is advisable to set this value higher when you notice significant fluctuations in the fuel data, while a lower value is recommended if the data from the device appears to be consistently smooth. For example, if you input the value 3, the system will process three data values at a time.
  The system provides tailored recommendations for Data Filtration Levels based on the specific sensor material and installation position, which significantly improves the accuracy of the readings.
• Apply To: This feature allows you to replicate the same fuel calibration settings across different devices or vehicles, streamlining the configuration process.

• • When you click on "Apply To," a dropdown menu will appear, allowing you to select the specific object to which you wish to apply the same calibration settings.
    
• If you want to configure Multiple Sensors,

• • Navigate to Profile.
    
    
    • In Fuel Tank, select Single or Multiple Tank according to your vehicle.
      If you select Multiple, then you have to add the No of Tanks available in the vehicle.
      
    • Based on the number of tanks you select, the Tank Number field will become visible during the sensor calibration process. This functionality allows you to specify the exact tank number for which you are calibrating, ensuring an efficient and accurate calibration of multiple sensors.
      

• Save the configuration by clicking on the Save 💾 icon.
