石油化工行业流量仪表选型初探

The Preliminary Investigation on Model Selection of Flowmeters for Petrochemical Industry

结合作者多年从事石化行业流量仪表应用的实践，阐述了流量计选型的基本原则与方法，并对诸如地下大口径流量测量、小流量低压瓦斯流量测量以及液化石油气的流量测量等难以解决的问题，提出了较为实用的选型技术。

Combining with the experience and practice on application of flowmeters in petrochemical industry the basic principle and method of selection of flowmeters are described. The practical technology of selection selection for some tough topics in flow measurement is stated, e. g. large bore underground flow measurement, low flow low pressure gas flow measurement and the flow measurement for liquefied petrochemical gas, etc..
