Effects on a wedge flowmeter installed downstream of a double elbow out of plane.

摘要

Precise flow measurement is a critical part of many industries including industrial, hydropower, petroleum, nuclear, and water/wastewater. Lengthy upstream piping is required for many flowmeters to obtain accurate results. Due to piping constraints, sub-optimal flow meter installations can occur. One of these conditions is the installment of a flow meter in close proximity downstream of a double elbow out of plane (DEOP). A DEOP can cause swirl to form in the flow and can cause inaccurate metering results due to the non-uniform flow and pressure conditions. This study investigated the effect of installing a differential pressure producing wedge flow meter downstream of a DEOP on the flow measurement. Computational Fluid Dynamics (CFD) was used for this study in conjunction with physical testing.
