Questions about differential pressure transmitters
Thread Content
I have a tank here that is 6 meters high. The differential pressure transmitter is installed at the bottom, while the pressure sampling port is located on the top of the tank. A pressure transfer pipe connects this port to the differential pressure transmitter, with both the inlet and outlet of the pipe being at the bottom. Should the pressure transfer pipe be connected to the high-pressure side or the low-pressure side? I appreciate your advice.
Either one should work. Specifically, check what the pressure is.
The pressure at the top is low, so it should be connected to the low-pressure port. High pressure at the bottom; connect to the high-pressure port
The range of the differential pressure transmitter is -500~2000 Pa, with one end of the transmitter exposed to the atmosphere.
There is no pressure tap at the bottom of the tank, and one end of the differential pressure transmitter is connected to the atmosphere.
That is called a pressure transmitter. Generally, differential pressure transmitters are used to measure pressure differences (liquid levels), etc. As mentioned on floor 6, connecting to the atmosphere at low pressure can also be used to measure the pressure inside the tank. I would like to ask what the pressure inside the tank is usually, and what the interstitial fluid is.
The pressure inside the tank is 0.002 MPa, and the medium is styrene.
Styrene tank, does it have a low-pressure nitrogen seal?
The tank is under nitrogen sealing, so it’s not at atmospheric pressure; it should be a double-flange level gauge
