SINOPEC Zhongyuan Petroleum Engineering Ltd., Puyang, Henan, 457001 Abstract: Metering is a key sector in natural gas trade. This paper reviews current situations of gas flowmeter calibration facilities in China and abroad, analyzes advantages and disadvantages of such facilities with different primary standards, and introduces the process flow, value dissemination and operation principle of Pigsar gas flowmeter calibration facility based on HPPP method. This facility is characterized by steady flow rate and high accuracy. However, due to technical limitations, the HPPP-based facility is not extensiv
