Condensate pot

In steam applications, transmitter protection element for accurate pressure measurement

For steam applications, condensate pots are essential. They are used to condense the fluid upstream of the differential pressure transmitter. Installed at the same height, they allow accurate measurement by maintaining a constant condensate height in the impulse lines above the differential pressure transmitter.

The condensation pot can also be used to protect the transmitter in the case of a flow measurement of a corrosive / aggressive fluid. In this case we speak of separation pots.

What is the purpose of the condensate pot and the separation pot? what is the difference between both?
  • The condensate pot is mandatory for accurate measurement in the case of steam applications. It is used to condense the steam systematically upstream of the transmitter; it thus maintains a constant condensate height in the impulse lines above the differential pressure transmitter; it therefore allows an accurate measurement of the differential pressure. Without a condensation pot, the vapor would condense randomly along the impulse lines to the transmitter (depending on the temperature drop undergone) and cause a differential pressure measurement error.
  • The separation pot can be used to protect the differential pressure transmitter in the case of a flow measurement of a corrosive and high-density fluid.
    It is filled with a buffer liquid (fluid A), in contact with the membrane of the transmitter to ensure the transmission of pressure, and immiscible with the high density fluid of the process (fluid B). The difference in density of the two fluids and the fact that they are immiscible allow a real separation between the transmitter side and the process side.
    Another way to prevent the transmitter diaphragm from contact with the process fluid is to use a capillary with the transmitter.
