The condensate is drained from the bottom ports with valve connection. The condensate water transmits the pressure to the transmitter, so that the transmitter itself is not in contact with steam. Condensate chambers are used as a barrier between the main line & the secondary instruments in the measurement of steam or other vapours which condense to a liquid state insuring compatibility with the secondary instruments. Installation can be done either in vertical or in horizontal lines between the primary component & the secondary instrument. It acts as a barrier to the line fluid allowing direct sensing of the flow conditions. Condensate pots should be mounted at the same level minimizing possible error that could arise due to unequal head of fluid in the connecting pressure lines. Usually the level in the chambers should be equal the total volume of condensate in the transmitter & the sensing lines.
