The four EEC orifice plates (0.2, 0.57, 0.66 and 0.75) were tested in the 250 mm meter run at the Westerbork natural gas test facility of Gasunie, using all the sets of pressure tappings. The basic discharge coefficients were measured and then a series of installation tests was carried out with the 0.57 and 0.75 plates using four different flow straighteners, located at three different distances upstream of the orifice plates.
