分析了可逆式孔板流量计和可变式孔板流量计的设计原理和实验结果。
The design element and the experiment result of reversible orifices and changing orifices low velocity flow is high.
The limitation of orifice plate is clarified in this paper, and the principle and design features of V-CONE are introduced. An actual application example is shown to illuminate advantages of V-CONE.
