本文简要介绍形成天然气脉动流的主要原因,并从流量计的动态特性讨论脉动流对孔板流量计测量精度的影响;指出解决计量误差问题的根本途径是消除脉动源。
This article briefly introduces the main reasons for forming pulsating flow of natural gas and discusses the influence of pulsatile flow on the measurement accuracy of orifice flowmeter from the dynamic characteristics of the flowmeter. It is pointed out that the fundamental way to solve the measurement error problem is to eliminate the pulsation source.
