Selection of urban gas roots flowmeter and turbine flowmeter

随着城镇燃气的发展,对天然气流量计量准确度的要求越来越高,目前,涡轮流量计和罗茨流量计是城镇燃气工商业用户的最主要的两种性价比较高的计量设备。文章综合分析了涡轮流量计和罗茨流量计的主要工作原理,提出两种设备的选型及安装方式。

with the development of urban gas, the demand for the measurement accuracy of natural gas flow is getting higher and higher. At present, the turbine flowmeter and Roots flowmeter are the two most important metering equipment of the urban gas industry and commercial users. The main working principles of the turbine flowmeter and Roots flowmeter are analyzed, and two are put forward. Type selection and installation method of plant equipment.
