Abstract

Aiming at problem of noise disturbance of vortex flowmeter caused by pipe vibrations and fluid turbulence

a kind of signal processing method based on MUSIC algorithm for vortex flowmeter is proposed.Measuring principle of vortex flowmeter is introduced

and vortex signal model under noise environment is built

moreover

basic principle of MUSIC is elaborated

vortex signals under various noise environment are simulated on this basis. Simulation results show that the proposed vortex signal processing method can suppress noise effectively and distinguish frequency point high precisely

and has good effect on improving performance of vortex flowmeter.
