Abstract

Vortex flowmeters are applied to the measurement of fluid flows where instruments with no moving parts and with wide rangeability are required. Process conditions influence the operation of a vortex flowmeter and fluctuations in the flow affect the complex phenomenon of vortex street formation. In the present study the signal taken directly from the sensor employed in an industrial vortex flowmeter is processed so as to discern the effects of various process conditions on the measurement signal. The implication is that signal processing and system identification techniques can be applied to enhance the quality of the measurement information provided to a supervisory control system
