摘要
随着世界天然气工业的迅速发展,天然气贸易的频繁,对天然气的准确计量要求越来越高。目前国内孔板流量计占90%以上,而影响该流量计计量准确度的因素很多,包括流体特性、仪表性能、安装、环境条件等方面,要解决或减少这些影响因素,必须加强管理、正确选用仪表及加强技术培训,提高人员素质。
With the rapid development of natural gas industry and its trade, measuring accuracy becomes a demanding work. Whereas the high occupancy of orifice meter in domestic gas measuring market, including fluid property, instrument performance, installation as well as ambient conditions which influence measuring accuracy , should be taken into account by means of management improvement, right selection of meters and technical training supports.
