Adaptive frequency measurement (AFM) for vortex flowmeter signal

This paper proposes a new adaptive frequency measurement method (AFM) for vortex flowmeter signals. Based on AFM, one can construct a new adaptive vortex flowmeter. Theoretical analysis and experimental results have proven that this method is practical for improving the measurement accuracy of the vortex flowmeter in practice use, and that this method can also be used in the other measurement and instrumentation systems.<
