EEC orifice plate coefficients project : 1983 NEL tests in water on thin orifice plates for EEC 100 mm assembly
The four EEC plates tested in air and natural gas facilities were recalibrated in the 100 mm meter run in the NEL cold-water test facility, using all three sets of pressure tappings. The results for the 0.57, 0.66 and 0.75 plates were in good agreement. For the 0.2 plate the fitted slopes were different, although the resulting lines crossed, so that results agreed to within 0.25%.
