Hello Guest,

Need more information. The measured differential pressure will vary with the height of the liquid in the vessel, AND with the density of the liquid.

  1. What is the liquid in the tank?
  2. What is its density?
  3. What is the range of your dP transmitter?

Answer these questions and we can probably help you.

Mike

And how is the -450mmH2O to be provided without loss of prime?
