The GP Flume is a volumetric flow flume with certified volumetric measurement capability. It is unique in the UK in terms of its size (25 m long x 2.4 m wide, operating depth 0.3-0.7 m) and flow measurement accuracy (±0.2%). Using the volume-time approach to measure flow rates, which is generally acknowledged to be the most accurate means available, it enables high accuracy data for the development of Standards. The flume is capable of generating flows up to 0.28 m3/s.
