説明

This paper describes the evaluation results on long-term stability of hydrogen gas meters in relation to the demonstration town project of pure hydrogen type fuel cells. We developed the gas meter calibration system that was traceable to the national gas-flow-rate standard in NMIJ/AIST. Four different type gas meters, which were an ultrasonic, a thermal type, a gear type, and a diaphragm type, were calibrated by the calibration system, and were evaluated at the demonstration town for three years. The results showed that an ultrasonic type and diaphragm type gas meters had good long-term stability, and that measurement uncertainties of these gas meters were small enough.
