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