采用 Ｄ Ｆ Ｔ 方法处理科氏质量流量计的信号是项新技术。本文提出一种频率跟踪方法，可以在不过零开始采样的情况下，实现整周期采样，保证频率和相位差测量的精度。仿真结果说明了本文方法的有效性。
The signal processing of the Coriolis mass flow meter using the DFFT method is a new technology. This paper presents a method of frequency tracking, which can achieve full-cycle sampling without over-zero sampling to ensure the accuracy of frequency and phase difference measurement. The simulation results show the effectiveness of the proposed method.
