国际气体流量测量技术的新进展

A NEW ADVANCE IN GAS FLOW MEASUREMENT TECHNOLOGY IN THE WORLD

文章从以下 6个方面综述了当今国际上气体流量测量技术的最新进展 ;①在加拿大新建成的TCC高压天然气大流量标定装置 ,它是目前世界上最精确的高压气体流量标定站 ;②全新的大流量气体流量传递标准———世界第一个工业用大型旋转活塞 (腰轮 )式校准仪 ;③新一代的气体超声流量计 ;④新型气体腰轮流量计 ;⑤用于天然气国际贸易输送的计量系统 ;⑥用于较小量点的新型天然气分配计量系统。

In this paper,the newest advance in the gas flow measurement technology in the world at present is summarized into following six aspects:(1)TCC high pressure and high flow rate calibration facility for natural gas newly built in Canada—the most accurate high pressure gas flow rate calibration station in the world at present,(2)all new high rate gas flow transfer standard—the first rotary piston poven for industrial use in the world,(3)new type ultrasonic gas flowmeter,(4)new type rotary piston gas flowmeter, (5)the metering system of gas transmission for international trade and (6)new type gas distribution metering system for small metering station.
