摘　　要：针对公称通径大于300mm的大管道气体流量测量过程中面临的困难,全面介绍并评述了满管式和点流速计型的插入式两类流量计的工作原理、优缺点、适用场合等.文末向用户推荐了几种较适用的气体流量计.Aiming at overcoming the difficulties which are met in gas flow measurement for large-sized pipelines of nominal bore size abovb 300mm, the operational principle, merits and demerits, as well as the applicable scope of two kinds of flowmeters, i.e. full pipe type and insertion type flowmeters are introduced comprehensively. Several flowmeters suitable for gas flow measurement are recommended finally.
