摘　　要：本文给出了一种基于谐振式环形测量管科里奥利质量流量计激振原理和信号检测方法 .采用了模拟乘法器解调出幅度信号 ,通过幅度信号计算出质量流量 .流体密度的检测是采用自激振荡原理和频率跟踪方法得到的 .The excitation principle and signal measurement method of a resonant loop-tube Coriolis mass flow meter are described in the paper. Mass flow rate can be obtained by multiplication simulator′s demodulating speed signal. Fluid density is measured by self-push resonant principle and frequency tracking method. The paper also presents the diagrams of excitation circle and measurement principle of the mass flow meter.
