Flow Conditioner Location Effects in Orifice Flowmeters

Orifice meters are used extensively to measure the high-volume flow of fluids (such as natural gas) through a pipe. Asymmetric & swirling flows (caused by nearby upstream bends, tees, or constrictions such as a partially closed valve) can make orifice meters inconsistent, so a flow conditioner of one kind or another is generally placed upstream between the meter & its disturbance. This report describes experimental results for 4 kinds of conditioners & 2 sizes of orifice meters, with various sizes of orifice plates & various degrees of roughness, using nitrogen gas.Flow Conditioner Location Effects in Orifice Flowmeters, was published 1994 under ISBN 9780788111211 and ISBN 0788111213.
