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

T. Morioka

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.
