Feasibility Analysis of Applying Hanning Window Interpolation Algorithm to Signal Processing of Vortex Flowmeter

This paper measures the vortex frequency with discrete spectrum analysis.However,since the discrete spectrum analysis is influenced by the fence effect,the frequency measurement accuracy is poor.The method of extending sampling time can improve the frequency measurement accuracy,but the operating efficiency of the system will be reduced.This paper considers applying the Hanning window interpolation FFT algorithm to measuring the vortex frequency.
