摘　　要：随着国家双碳政策的实施,煤改气工程的不断深入,各地市工业、民用天然气总量的不断增加,天然气流量计量系统计量性能和系统运行状态已涉及供需双方的经济利益及国家能源计量安全。为保障天然气管道输送计量准确可靠,需在检定周期内实施在线期间核查工作,确保系统运行准确可靠。本文在天然气计量系统现场在线期间核查方法的基础上,结合芜湖中燃实例,提出流量计现场核查方法的管理及应用。With the implementation of the national dual-carbon policy,the continuous deepening of the coal-to-gas project,and the continuous increase of the total amount of industrial and civil natural gas in various cities,the measurement performance and operation status of the natural gas flow measurement system have involved the economic interests of both the supply and demand sides and the national energy measurement security.In order to ensure the accurate and reliable measurement of natural gas pipeline transmission,it is necessary to carry out online verification during the verification cycle to ensure the accurate and reliable operation of the system.In this paper,based on the on-site on-line verification method of natural gas metering system,the management and application of flowmeter on-site verification method are put forward in combination with the example of middle combustion in WUHU.
