Condensate Pots
Stable reference legs for steam-service differential pressure measurement.
View Specifications
The Condensate Pot, also called a Steam Pot or Condensate Chamber, is a small vessel installed in the impulse line of a differential pressure (DP) measurement system on steam service. Steam condenses inside the pot and forms a constant liquid leg (water seal) of fixed height. This does two things: it keeps hot steam from reaching the transmitter, and it keeps the liquid leg equal on both sides of the DP measurement. When the pots are installed at the same elevation on both impulse lines, the liquid legs cancel each other out, so the transmitter reads only the true differential pressure. Condensate pots are used with orifice plates, venturis, and nozzles for steam flow measurement, and with DP level transmitters on boiler drums and steam-heated vessels. They are supplied with vent, drain, and fill connections as required, in a range of materials, pressure ratings, and end connections.

Frequently asked questions.
Why is a condensate pot needed in steam service?
Transmitters and impulse tubing cannot be exposed directly to high-temperature steam. A condensate pot lets the steam condense into water, which forms a liquid seal that protects the transmitter from the heat. It also keeps the impulse lines filled with liquid at a fixed height, so the measurement is stable and repeatable.
How should condensate pots be installed?
For DP flow measurement, install the two pots at exactly the same elevation, close to the process taps and above the transmitter. This makes the liquid legs equal on both sides, so their static heads cancel out and the transmitter reads only the differential pressure across the primary element. Unequal heights cause a measurement error. Impulse lines should slope continuously and be free of air pockets, and the pots should be filled with water before start-up.
