If the sensor returns analogue signal proportional to fuel level it can be connected to {{{model|FMB1YX}}} Analog input. After connection to the tank fuel level sensor a calibration is needed because most fuel tank sensors are not linear. Calibration is performed by measuring voltage values resulting from the volume of fuel in tank.
