Fuel flow transducers came to be used in aircraft around the early 70s. Vibration of an aircraft engine. It also had to meet the important FAA regulation regarding blocked rotor pressure drop which could not be more than 1.5 times the spinning rotor pressure drop. Fuel flows can be measured via a conventional rotor-based fuel measurement system or, via the more modern fuel flow transducer - a digital-technology based system. The advantage of this new technology fuel flow measurement system is that, it is impervious to pressures and therefore the data is more accurate.

The fuel flow transducer works upon a vane RPM S ... Read more »
