差压流量测量技术简单、易懂,但量程比受到限制,且功率或压力损失大。本文介绍另外几种不同型式的流量计。火力发电厂的流量测量,目前有80%是利用流体通过管内的节流元件(通常是孔板)所造成的差压来计量的。其主要优点是,这种具有简单几何形状的一次元件对流体作 Differential pressure flow measurement technology is simple and easy to understand, but the range ratio is limited, and the power or pressure loss. This article describes several other types of flow meters. At present, 80% of the flow measurement of a thermal power plant is measured by the differential pressure caused by the flow of fluid through a throttling element (usually an orifice) in the pipe. The main advantage is that this primary element with a simple geometry makes a fluid
