ANALYSIS OF THE SENSOR SIGNAL FROM A VORTEX FLOWMETER TOT RECOVER INFORMATION REGARDING THE FLOW REGIMES

Abstract:
The paper discusses the effects of non-standard flow regimes on the performance of vortex flowmeters and the methods of analysing the vortex sensor signal to detect the presence of these spurious conditions in the flow, and swirling flow in particular.
This study shows that the amplitude and frequency fluctuations embedded in vortex sensor signals carry much useful information about system conditions and fluid flow regimes which can seriously impair the accuracy of measurement. The necessary signal information can be recovered by analysing the unconditioned raw vortex sensor signal i.e. utilizing data regarding fluctuations in signal amplitude and periodicity.
