Research on Frequency Tracking Method in Signal Processing of Coriolis Mass Flowmeter

Xu Kejum,Jiang Hanke,Su Jianhui,Chen Rongbao (Hefei University of Technology,Hefei 230009)  
It is a new kind of technique that the signals of Coriolis mass flowmeter is processed by means of DFT method.A frequency tracking method is proposed .The synchronism sampling is achieved to improve the measuring precision of frequency and phase difference.The results of simulation have proven the effectiveness of the method presented in this paper.
