环式离心流量计的应用误差分析

Application of accuracy analysis for annulus centrifugal flowmeter

介绍了环式离心流量计的原理 ,以及其结构尺寸与介质的流速、密度、粘度、“二次流”等对测量误差的影响。提出了消除及减少这些因素对测量误差影响的解决办法。

This paper introduces the principle and structure of the annulus centrifugal flowmeter. It is concluded that the measurement accuracy will be affected by flow medium, including velocity, viscosity, secondary flow,the measures to reduce the affections are suggested. The application range of the annulus centrifugal flowmeter is also provided.
