Hello,
Thank you for your inquiry.
Calibration is being performed by measuring voltage dependence on volume of fuel in tank. Simple table must be made. In first column must be a voltage of AIN, in second a fuel level (Liters) in gas tank. While measuring vehicle engine should be working and FM should be connected to vehicle battery. 10% resolution is recommended for better detail.
After making table the results must be approximated by function:
Coefficients must be entered in appropriate fields in TAVL Server Management and values displayed in TAVL application will be shown in liters. If you using Teltonika server, please send Fuel Tank calibration table to Teltonika sales manager. We will calculate and enter coefficients for you.
Hope this will help.
Best Regards.
