Abstract
An edge of a piezoelectric disk transducer is biased into an external wall of a flow passage by a spring. The disk is then driven at a radial mode resonant frequency to project acoustic energy into fluid flowing in the passage. This arrangement is compatible with several types of fluid flow sensors such as transit time, Doppler, and vortex shedding flow meters.
