|
Abstract This paper introduces the basic method of calibrating high pressure gas flowmeter using high pressure gas flow standard device. The general situation of high pressure gas flow standard device at home and abroad is also expounded. In the paper, we also analyzed the advantages of the loop track device over the straight line arrangement. We also talked about the key technologies such as the selection of working medium, the traceability of the device and the controlling method of temperature and pressure during the design and construction of the high pressure loop gas flow standard device. Finally, the uncertainty analysis of typical high pressure loop gas flow standard device is given.
