Condensate and Seal Pots

Condensate pots catch and hold condensate and foreign material, keeping manifold orifices clean. They sit upstream of the instrument, between the primary element such as a flow meter and the secondary instrument such as a transmitter or gauge, and have a bottom drain for cleaning. They can be installed on vertical or horizontal lines, and pairs should be mounted at the same level to avoid errors from an unequal head of fluid.

Seal pots

Seal pots hold a liquid seal between the instrument and the process, keeping the liquid level in the impulse lines constant. In boiler drum level measurement, for example, steam condenses in the seal pot and fills the impulse line, and the pot lets surplus condensate drain back to the source so the level in the line stays constant.
