Abstract
A vortex-shedding flowmeter uses two ultrasonic transducers to generate an acoustic beam at a selected carrier frequency. Vortices generate fluid oscillations that are detected when they pass through the beam and induce phase changes representative of fluid flow rate. In an improved vortex-shedding flowmeter each of the transducers is connected to a separate transformer and the outputs of the two transformers are interconnected to yield the phase change.
