孔板流量计在煤气计量中的应用

The Application of Orifice Plate Flowmeter in Measuring Manufactured Gas

本文论述了温度、压力自动补偿和测量原理以及安装要求,分析了孔板流量计在使用后测量精度下降的主要原因,并指出了改进途径。

This paper discusses the rquirments for installation and the principles for automatic compensation of the temperature and the pressure as well as measurement. The main cause for which the accuracy of measurement goes down after the orifice meter goes into operation is analysed and ways for improvement are pointed out.
