摘　　要：在石油、石化和化工生产中,经常使用转子流量计和差压式流量计.为了更好对这两种流量计区分,首先对比了转子流量计与差压式流量计的工作原理,进而对两种流量计的流量方程进行推导,最后又比较了两种流量计的优缺点.The rotameter and differential pressure flowmeter were used frequently in oil, petrochemistry and chemical production. In order to distinguish the two types of flowmeters betterly, firstly the working principle of rotameter and differential pressure flowmeter were compared, then the flow equation for two kinds of flowmeters were deduced, finally, a distinction between the advantages and disadvantages of two kinds of flowmeters was made.
