What is a Fuel Flow Transducer in Aircraft

The fuel flow transducer works upon a vane RPM Sensor that is usually located behind the fuel filter and works in combination with the manifold air pressure (MAP). The fuel flow transducer produces a current-pulse signal from an opto-electronic pickup that's fitted with a preamp. The signal amplification enables it to measure fuel flow that is as low as 0.3 gal/hour and this makes it more accurate than the conventional fuel flow measuring systems.
