Description

The Maretron M4AR is a fuel flow sensor that works as an accessory to the FFM100 Fuel Flow Monitor. When fluid (fuel) passes through the sensor, internal rotors turn, and magnets within these rotors pass across sensors on a circuit board. The pulses generated are transmitted to the FFM100, which calculates the fuel flow rate. It is important to order the correct size sensor for your engine, as fuel flow sensors are not returnable.
