- Abstract:
- The volumes of a storage tank and a temperature control loop of the high pressure gas flow standard system in KRISS were increased about three times to calibrate large flow meters and to test the flow capacity of control valves. Sonic nozzle bank consisted of 15 sonic nozzles (10, 13, and 19 mm diameters) is used as reference flow meter. The performance of this large air flow calibration system was evaluated.
