Flow rates normally up to 120.000 m3/hr (less in summer) at pressures up to 50 bar can be switched to flow through a test section after being measured by five orifice meter runs in parallel. The maximum Reynolds number obtained in a 200 mm test line was 1.5 x 1.0 E7. Full details of instrumentation and uncertainty estimates (overall 0.3%) are given.
