摘要
天然气流量计量是天然气工业生产中十分重要的一个环节 ,从气井井口到用户 ,是一个全密闭的系统 ,计量的准确与否 ,不仅直接影响各工艺过程 ,也将对天然气的产、供销等各个环节产生重要的影响。因此 ,天然气流量计量一直是人们十分关注的问题 ,流量测量技术及仪表得以大力发展。着重介绍广泛使用的孔板流量计。
Metering of natural gas is one of the most important links of nature gas industry. The gas production system, From well to user, is closed. Metering accuracy not only influences the each procedure of gas production process directly, but also has vital effects on each link of gas producing, supplying and selling. Natural gas metering technology and instrument has been developed rapidly. The properties and optional principles of the widespread used metering instruments, such as orifice flow meter, turbine flow meter and vortex flow meter are stressed in this paper.
