Abstract
Based on the sensing mechanism of Coriolis mass flowmeter and analyzing signal spectrum in actual working, the novel applied method is devised for phase difference detection. The improved FIR filter is designed and used for filtering original signals, so the noise is restrained effectively and the measurement precision of the mass flowmeter is guaranteed. Meanwhile, the dynamic response performance of the system is improved by this novel method. The experimental results showed that the method is well worthy applying.
