Abstract

Six thin and six thick EEC orifice plates were calibrated in the 250 mm meter run in the NEL cold-water test facility, using all three sets of pressure tappings. The 0.75 plates were tested with and without a Zanker flow straightener 42D upstream. Differences were not systematic. Pitot traverses, which were made at the plane of the orifice plate with and without the straightener, showed fully developed velocity profiles.
