Flow Conditioning and Profile Fundamentals
In this article, Russell reviews flow profile fundamentals, five end-user application considerations that impact thermal mass flow meter accuracy, and explores the use of flow conditioning to improve a flow meter’s accuracy.
Introduction
The velocity profile is used to determine the flow rate of a fluid flowing within a pipe. If the fully developed profile changes, a thermal mass flow meter’s accuracy decreases. Additionally, five application factors require consideration as they affect the meter’s accuracy; one of these includes the upstream straight run distance, which changes the flow profile. In many cases, flow conditioning, a process of synthetically creating a more uniform flow profile, is necessary when upstream straight run lengths are not available to achieve a sufficiently developed flow profile.
