亚音速-音速文丘里智能流量计

The Intelligent Venturi Flowmeter with Subsonic Speed and Sonic Speed

介绍一种新型差压式流量计 ,其根据超临界和亚临界流动状态下的不同流量特性 ,使之同时具有音速 -亚音速文丘里管与计算机构成的流量计的功能 ,从而扩大了流量测量范围 。

A novel d/p flowmeter is introduced. In accordance with the different flow characteristics under supercritical and subcritical flowing status the flowmeter provides functions from both sonic and subsonic Venturi tube and computer based flowmeter. Thus the measuring range is extended and the problem of correcting the measuring deviation under varying operation status is realized.
