Pressure transducer based fluid velocity sensor
2007
Pelletier, M.G.
The invention consists of a pressure transducer based air velocity sensor that has been optimized for use in metal ducts. The fluid flow velocity is determined by measuring the propagation delay of a direct path pressure wave signal transmitted through the fluid as a function of a frequency difference rather than as a phase delay measurement. This system electronically removes multi-path signals from the measured signal, thereby obviating the requirement for installation calibration.
