Abstract: Several new technologies must be developed to complete the infrastructure for the utilization of hydrogen gas in a hydrogen society of the near future. One of them is the flow meter to measure the flow rate of hydrogen gas when filling it in the storage tank of a fuel cell vehicle at a gas station. The important point is that the flow meter used at a gas station is a transaction meter, which is required to have a superior reproducibility. For example, no adjustment of the flow meter is allowed during the period provided by the metrology law. Furthermore, the maximum pressure of hydrogen gas in the storage tank is going to be raised from 35 MPa to 70 MPa to extend the range of the vehicle, because its range is only about half that of gasoline vehicles when the maximum pressure of hydrogen gas in the storage tank is 35 MPa. At the present time, a coriolis type flow meter is used for a flow measurement of a hydrogen gas at gas stations. However, a coriolis type flow meter with oscillating mechanical parts will have to be evaluated its reliability at such a high pressure for long term use.
