腰轮流量计低压标定高压运行误差因素探讨

Error Analysis of the Low-Pressure Calibrating and High-pressure Operation for the Rotz Flowmeter

分析并验证了流量计因低压标定高压运行所产生的附加误差，通过引入压力修正系数Ｃｐ对仪表值进行定量修正，并在实际生产中取得一定的经济效益和社会效益。对误差的消除提出了相应的改进途径。

This article analysis the extra error resulting for the low-pressure calibrating and high -pressure operation of the flowmeter Through the use of pressure modification coefficient Cp, the meter can be modified qualitatively and some economic reward and social reward the been gained in the production site. Also some modification approach has been suggested in order to eliminate the error.
