INTERACTION BETWEEN ULTRASOUND AND STREAMING FLUID IN VORTEX SHEDDING FLOW METERING
Christian Filips, Volker H. Hans
Abstract:
In the past in vortex-shedding flow meters pressure sensors in combination with big bluff bodies have been used. In the last few years the dimension of bluff bodies were reduced using ultrasound sensors due to higher sensibility. The frequency of periodically generated vortices are directly connected to the flow velocity. The signals are modulated in amplitude as well as in phase. The information are in the sidebands of the ultrasonic signal. Different carrier frequencies in combination with different dimensions of bluff bodies are examined.
