Kaidi KD YELJ Integral Orifice Flow meter for chemical industry
YFLJX series restrictor orifice plate is a concentric orifice plate, used to limit the flow of fluid or reduce fluid pressure. The fluid passing through the orifice plate will produce a pressure drop, and the flow rate through the orifice plate will increase with the increase of the pressure drop. But when the pressure drop exceeds a certain value, that is, exceeds the critical pressure drop, no matter how the outlet pressure decreases, the flow rate will maintain a certain value without increasing. The restrictor orifice is used to limit the flow of the fluid or reduce the pressure of the fluid according to this principle
▲ Flow can be limited
▲ Can reduce stress
▲ Simultaneous current limit and pressure reduction
▲ No need to take pressure hole to measure differential pressure
