Effects of Upstream Butterfly Valve on the Accuracy of a Vortex Flow Meter

• Abstract:

  The problem of accurate determination of volumetric flows by means of vortex-shedding flowmeters in the case of upstream disturbances caused by an butterfly valve, installed 5 diameters upstream of the meter, has been studied. To this end, the flow about the bluff body used in the presently studied vortex-shedding flow meter, having DN25 (simulation) and DN50 (experiments) test sections, was investigated experimentally and numerically.
