The main purpose of condensate pot is to catch and hold condensate and foreign material. This prevents damage to the metering system and/or manifold.
The condensate may be drained from the bottom valve connection.
Condensate chambers are used as a barrier between the main line and the secondary instruments in the measurement of steam or other vapors which condense to a liquid state insuring compatibility with the secondary instruments.
They can also be used to cool down very high temperature liquids.
Seal pots are installed where the line fluid is corrosive or viscous to the extent where it cannot be permitted to contact the secondary instrument (transmitter or gauge) thereby acting as a liquid barrier between the line fluid and the condensate.
