一、概述双翼式均速管流量计是一九七二年上海自动化仪表一厂和上海工业自动化仪表研究所联合研制的一种基于变压降原理的差压感受元件。主要用于大口径管道内气体或液体的流量测量。其结构比较简单,安装方便,适合于批量生产。性能稳定、可靠,复现性好,具有一定的测量精度,并且还可用于非对称管流的流量测量,压力损失较节流装置小得多。几年来,通过大口径管道内的烟气
First, an overview of two-wing mean-velocity pipe flow meter is a 1972 Shanghai Automation Instrumentation Factory and Shanghai Institute of Industrial Automation Instrument jointly developed a variable pressure drop principle of differential pressure sensing element. Mainly used for large diameter pipe gas or liquid flow measurement. Its structure is relatively simple, easy to install, suitable for mass production. Stable performance, reliable, good reproducibility, with a certain degree of measurement accuracy, and can also be used for asymmetric flow measurement tube flow, pressure loss is much smaller than the throttling device. In recent years, through the large-diameter pipe flue gas
