This paper presents new experimental data for orifice meter expansion factor tests flowing natural gas through a 75 mm (3-inch) diameter orifice meter tube for values of the orifice diameter ratio (β) between 0.60 and 0.75. The tests were performed in the Low Pressure Loop (LPL) of the Metering Research Facility (MRF) at Southwest Research Institute (SwRI). The new data complement previously reported results for 100 mm (4-inch) and 150 mm (6-inch) meter tubes for β values between 0.20 and 0.60.
