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 the natural gas industry in the world, the trade of natural gas is frequent, and the demand for accurately measuring natural gas is getting higher and higher. At present, the domestic orifice flowmeter accounts for more than 90%, and many factors affect the accuracy of the flowmeter measurement, including fluid properties, instrument performance, installation, environmental conditions, etc., to address or reduce these factors, we must strengthen management, correct Use of instruments and strengthen technical training to improve the quality of personnel.
