Performance evaluation test of Coriolis flow meters for hydrogen metering at high pressure

• Abstract:

  This paper describes the results of performance evaluation of Coriolis flow meters from various manufacturers in high-pressure hydrogen actual flow using a calibration system with critical flow Venturi nozzles as a reference. The calibration system consisting of five nozzles was developed to calibrate the flowmeters by high-pressure, high-flow-rate hydrogen gas. The performance evaluation test of the Coriolis flowmeters wasconducted at maximum pressure of 70 MPa, gas temperature of 0 °C and -40 °C, and flow rate range from 0.5 kg/min to 3.0 kg/min. It was confirmed that the instrumental error of most of the DUTs tested in this paper was within ± 2.0 %, although the instrumental error tended to be slightly larger at -40 °C in the small flow rate range.
