Combined Processing of Electronic Signal of Vortex Flowmeter

M. Music, M. Ahic - Djokic
Abstract:
Passing through the vortex street, behind the bluff body, amplitude and phase modulation of ultrasonic wave happen at the same time. Level and form of modulating signal depend of mean flow velocity and shape and size of vortices. In this paper, one combined method of signal processing, converted ultrasonic to electronic signal, using amplitude or phase demodulation, has been presented. Choice of processing depends on the mean flow velocity. Also, experimental results, using prototype ultrasonic vortex flowmeter PVMP50, based on noticed method have been presented.
