The quality and time of natural gas flowmeter primary verification technology based on static mass method can be traced to the national benchmark of quality and time, so the technology can achieve higher accuracy of measurement and has been widely applied. The uncertainty is the measure index of metering and verification accuracy of natural gas flow, the uncertainty of the static mass method is analyzed and calculated in-depth, on this basis, key measures for reducing uncertainty of the primary flow verification method are proposed. The analysis lays foundation for popularization and application of this technology in natural gas flow metering and verification.
