Problems with the installation of differential pressure level transmitters
Thread Content
Gentlemen, I would like to ask: for a differential pressure level transmitter, is it possible to install the pressure tapping for the gas phase on the top of the tank?
Sure, no problem. But when calculating the relationship between differential pressure and liquid level, it is necessary to determine what differential pressure corresponds to 100% liquid level, rather than assuming that the maximum differential pressure corresponds to 100%
It’s best to follow the instructions to avoid taking responsibility. For reference.
Those with double flanges can be connected to the tank top in the gas phase
If the pressure inside the tank is at atmospheric pressure, the low-pressure side is set to atmospheric pressure, and it can be installed either on the top or bottom of the tank. There’s no need to say anything about sealing the jar
