An EEC 600 mm orifice plate assembly, accompanied by six orifice plates with nominal diameter ratios of 0.75, 0.66, 0.57, 0.50, 0.37, and 0.20, as well as a special plate for pipe friction tests, were delivered to NEL. The orifice plates were calibrated in the NEL large water flow facility. A pilot traverse assembly was used to measure the velocity profile in the test section on two axes at the plane of the orifice plate carrier. Pipe friction measurements were also taken, these tests being made with the special plate, diameter ratio 1.0, fitted in the orifice plate carrier.
