Flow Rate Measurement Technology for High-Pressure Hydrogen Gas

Abstract

The results of research and development and the latest trend on flow rate measurement technology for high-pressure hydrogen gas are introduced. Two kinds of test apparatuses, which were a gravimetric method and a master meter method, were developed for evaluating the metering performance of hydrogen dispenser in the hydrogen refueling station. These technologies were reflected to the industrial guideline and standard. The Japanese standard will be suggested to the international recommendation in near future. These actions and results are leading the world and will contribute to the realization of hydrogen society in Japan.
