Differential pressure flow rate
Thread Content
Differential pressure is used to measure flow rate; the pressure lead pipes pass through an isolation tank before going to the transmitter and the drain valve. The two drain valves lead to a pipe that goes upward; what kind of pipe is this, and is it combined with the drains from other transmitters? It’s still the isolation fluid that originally came from above.
I don’t understand; can waste be discharged this way?
It’s not for waste discharge; it depends on what the medium is – the backwash pipeline should be connected instead
It should be backwashing; blockages in the pressure guiding system can be cleared in this way.
Asked clearly – connect to the isolation fluid system. The inside of the tube is filled with isolation fluid.
Used to inject flushing oil or isolation fluid for anti-clogging purposes, or when the medium cannot be easily discharged
