The pre- and post-test dimensional measurements of 250 mm orifice run, thick plates
The six EEC thick 250 mm orifice plates were dimensionally checked before and after flow calibration tests were carried out in the NEL cold-water test facility. No measurable changes were found in the flatness, downstream level, surface texture and concentricity of the plates. A slight increase in the edge radii was detected, with the 0.375 plate being outside the allowable tolerances.
