Abstract: Flow conditioning is one of the most critical aspects dealing with any type of volumetric flow metering. Flow conditioning is the final buffer between the flow meter and the upstream piping layout and is responsible for eliminating swirl, restoring flow symmetry and generating a repeatable, fully developed velocity flow profile. Even though modern advancem ents have resulted in low uncertainty, high repeatability device s that are effective across a range of flow rates, proper utilization of flow conditioner is still required to maximize the meters performance, diagnostics and ensure the most stable long ter m flow measurement. All flow conditioner technologies are not made equal , as com monly used designs such as AGA tube b undles and straightening vanes can actually cause mor e measurement problems than they resolve. This paper will focus on two main types of flow conditioners perforated plate systems and tube bundles .
