我国近年来在使用部门的推动下,靶式流量计得到迅速的发展。京津唐电网随着燃油锅炉的增加,靶式流量计在燃油流量测量上得以应用并拟采用靶式流量计解决电厂脏污流及往复式脉动流的流量测量问题。这里,对靶式流量计的原理,计算公式,设计及使用方面的有关问题作了介绍,供各厂参考。当前通常流行的计算公式是以“管道内介质流速乘以管道与靶问的环形截面积”为基础,进行推导的。我们认为这样处理是不合适
In recent years in China, driven by the use of departments, the rapid development of the target flowmeter. Beijing-Tianjin-Tangshan Power Grid With the increase of oil-fired boilers, target-type flowmeters are applied to fuel flow measurement and target-type flowmeters are proposed to solve the problem of flow measurement of smudge and reciprocating pulsating flow in power plants. Here, the principle of the target flowmeter, calculation formula, design and use of the related issues were introduced for the factory reference. The currently popular formula is derived based on “the flow rate of the medium in a pipe multiplied by the annular cross-sectional area of the pipe and the target.” We think it is inappropriate to do so
