基于科里奥利质量流量计动态数据测量研究

The Research of Dynamic Measurement Based on Coriolis Mass Flow Meter

科里奥利质量流量计的工作原理是流体作用于测量管产生一微弱力,该力的大小可反映质量流量的变化。本文介绍该微弱力的信号数据采集、动态测量的工作原理,及如何使得质量流量计精确度达到千分之二。

The operational principle of Coriolis mass flow meter is that fluid generates acting force to the measuring tube, and the size of this acting force reflects the change of mass flow. This article provides the information on the operational principle of the small-signal dynamic measurement system of the data acquisition of this mass flow meter, and makes the accuracy degree of mass flow meter increased by a wide margin.
