Orifice Meter Installation Effects: Measurements of Axial Mean Velocity,Turbulence Intensity, and Swirl Profiles Upstream of the Meter Tube Installation. GRI Metering Research Facility Program

摘要

The test series described in this memorandum is part of the Metering ResearchFacility Orifice Meter Upstream Effects Research Program, conducted to investigate the benefit and feasibility of fitting flow conditioning devices into new gas flow metering installations as well as retrofitting these devices into existing installations to assure proper upstream flow conditions. This report describes the orifice meter installation and documents the measured values. Because of the conclusions reached as a result of this test series, it is recommended that future orifice meter or turbine meter installation effects tests use a 19-tube conditioner at the exit of the stagnation bottle.
