The adaptive measurement of frequency and its application to vortex flowmeter
Abstract
This paper studies a new adaptive measurement of frequency method (AMF) for vortex flowmeter signal processing. It combines the adaptive filtering with power spectrum analysis. This method is especially suitable for measuring or estimating the frequency of signal such as vortex flowmeter signal with disturbance. Theoretical analysis and experimental results have proved that this method is efficient for improving the measuring accuracy of vortex flowmeter and can also be used in other measuring and instrumentation systems.
