Maretron Flow Sensor 10-100 LPM/2.6-26.4 GPM Fuel. 6-26.4 GPM When fluid passes through the sensor the rotors turn. Magnets which are located in the rotors will pass across sensors in the sensor circuit board. Pulses from these sensors are transmitted to the FFM100 which performs flow rate calculations based on the received pulses.
