The six EEC thick orifice plates were tested in the NEL cold-water test facility in the 100 mm meter run, using all three sets of pressure tappings. The results were compared with the ISO 5167 predictions and the coefficients obtained for the EEC thin plates. The results for the thick plates were consistently below those for the thin plates by around 0.3% and were generally just below the ISO values.
