摘　　要：天然气实流检定装置中,原级标准装置是整个检定装置的最高级标准。介绍了国际上常用的几种气体流量原级标准装置,比较了HPPP法和mt法两种原级标准的量值溯源,分析了原级标准装置的不确定度因素,以此作为工程应用的基础,建设国家级天然气实流检定站。Primary standard device is the most advanced standard of whole calibrating device in actual flow calibration device of natural gas. Several primary standard gas flow devices commonly used world-widely are introduced. The traceability for two primary standards of mt method and HPPP method are compared. Uncertainty factors of primary standards devices are discussed. It can be used as basis of engineering applications to construct national actual flow calibration station of natural gas.
