容积式流量计在大流量煤气计量中的应用

Application of Volumetric Flowmeter to Measure Large Flow Gas

指出了孔板流量计在使用中存在的问题；对容积式流量计在出厂大流量煤气计量中的应用进行了探讨，并结合现场，对其工作特性、精度、误差进行了分析；并制定了一个利用智能仪器进行温度、压力补偿的初步方案。

Some problems of the orifice flowmeter in use is pointed out. The application of the volumetric flowmeter to measure large flow gas is probed. Combining the worksite, its operating property, precision and instrumental error are analysed.The initial plan for making use of the intelligent instrument to compensate the temprature and presure is drawed up.
