Improvement on Coriolis Mass Flowmeter Closed-loop Control Based on Analysis of its Open-loop Characteristics

摘要：

Coriolis Mass Flowmeter(CMF) provides direct measurement of mass flow and is generally regarded as the most accurate and precise flow technology in industry. The precondition of its precision measurement is to maintain the flowtube vibration at its natural frequency,which is realized by closedloop control. Based on the CMF open-loop characteristic test experiment,this paper analysis the experiment data and some problems that arisen during the experiment,and then introduces several methods to improve the performance of digital CMF closed-loop control.
