__TOC__
==Introduction==
Fuel tracking is one of the key challenges of fleet management. If the vehicle has a factory installed Analog Fuel Sensor, there is a solution that does not require any additional equipment - you can connect the device via AIN to read the fuel data straight from the sensor. Teltonika offers a wide range of devices with an analog input to which the analog fuel sensor can be connected.
Instructions of connection and configuration are listed below.

To add a new tank fill row "''Add row''" must be clicked. "''Clear rows''" is for clearing all the rows. By clicking "''Export''" data will be exported to .csv file. To recalculate polynom "''Calculate''" must be clicked. Clicking "-" on the selected row will remove the row.

'''NOTE''': LLS calibration will not send the fuel data in liters through AIN, it is intended to help calculate the polynomials that are used in this formula: [[File:Formula AFS.png]] to calculate (mV) to Liters, where x is the AIN value.

To do that, go to I/O elements and select Analog Input 1 to Low/High priority. The Operand of the I/O element should be left as Monitoring.

You will see changes in fuel level expressed by the equivalent voltage read from the fuel sender wire to the Analog Input of your Teltonika device.
