ABSTRACT:
A plurality of piezoelectric sensors are disposed in a spatial array around the ports of an injection nozzle. Separate electrical signals proportional to the instantaneous momentum of fluid discharged from the injection nozzle and impacting on each of the sensors are used to calculate the instantaneous momentum and mass flow rate of fluid impacting each of the sensors.
