进口孔板流量计原理及用途Principle and purpose
孔板流量计是将标准孔板与多参量差压变送器（或差压变送、温度变送器及压力变送器）配套组成的高量程比差压流量，充满管进口孔板流量计原理及用途.jpg道的流体流程管道内的节流装置，在节流件附近边成局部收缩，流速增加，在其上、下游两侧产生静压力差（如图）。在已知有关参数的条件下，根据流动连续件原理和伯努利方程可以推异出辨压与流量之间的关系（流量愈大，所产生的压差愈大）而求得流量。
Orifice plate flowmeter is a high range ratio differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter). The throttling device in the fluid flow pipeline that is filled with the pipeline locally contracts near the throttling component, increases the flow rate, and generates a static pressure difference on both upstream and downstream sides (as shown in Figure 1). Under the condition that relevant parameters are known, the relationship between differential pressure and flow rate can be inferred based on the principle of flow continuity and Bernoulli equation (the larger the flow rate, the greater the pressure difference generated) to obtain the flow rate.
