摘要
对某计量偏差问题进行探讨,提出腰轮流量表计量过程中天然气窜流现象。分析天然气在腰轮流量表内反向流动产生的原因、判断方法以及预防措施,提出了腰轮流量表设计和安装的建议。
A measurement deviation problem is discussed. The natural gas by-passing phenomenon during measurement with Roots flowmeter is put forward. The cause of reverse flow of natural gas in Roots flowmeter, the judgment method and prevention measures are analyzed. Suggestions on design and installation Roots flowmeter are taken.
