智能型涡街流量计在合成氨厂天然气流量测量上的应用

Application of Intelligent Vortex Flowmeter in the Measurement of the Flow Rate of Natural Gas in Synthetic Ammonia Production

天然气是一种多组分、复杂的混合气体，其流量的计量过去采用同心直角孔板差压式流量测量方式，由于多种因素易引起测量误差。从涡街流量计简单的工作原理，使用实例介绍应用涡街流量计测量天然气流量，提高天然气计量的准确度。

The differential pressure flowmeter substituted for the vortex in the production synthetic ammonia to improve the measuring accuracy for the flow rate of natural gas.
