科氏质量流量计选型的几点体会

Some Experience for Coriolis Mass Flowmeter Selection

科氏质量流量计正常工作时,测量管振动使管内测量介质产生科里奥利力。科里奥利力越大,流动介质与测量管壁间的摩擦力就越大,产生的流量计压损也越大。而科里奥利力的大小与测量介质的流速成比例关系。所以科氏质量流量计选型时应当考虑测量介质流速的影响。

When coriolis mass flowmeter works normally, it＇s measuring tube vibrating would make coriolis force to measuring medium in the tube. The coriolis force was more larger, the friction force between flowing medium with tube well was more larger, the pressure loss of flowmeter was more larger. And the coriolis force was relevant to the flow rate of measuring medium. So affect of the flow rate of measuring medium should be considered when selecting coriolis mass flowmeter.
