What is condensate pot?

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.

How does a condensing pot work?

The theory of operation for condensate pots is that between the process taping and the pot is a steam vapor. Between the pot and the differential pressure transmitter is water (liquid) which eliminates any measurement errors due to a liquid/vapor mix at the measurement device.

How do you install a condensate pot?

Installing condensate pots

1. Connect the condensate pots to the high pressure (HP) and low pressure (LP) impulse lines of the transmitter.
2. Install the pots horizontally, although some vendors say you can install vertically too.
3. Make sure you install both at the same level to avoid affecting meter performance.

What is an impulse line in instrumentation?

Small diameter tubes or pipes commonly called impulse lines are used to transmit the pressure signal from the process to the transmitter. In some applications, these impulse lines can become plugged with solids or frozen fluid in cold environments, effectively blocking the pressure signals (Figure 1).

Why do you need a condensate pot in a steam boiler?

They are used to ensure that the condensation of steam in the impulse lines does not impair the ability to accurately sense differential pressure fluctuations and to minimize gauge line error because of differences between pairs of impulse lines.

How is a condensate pot used to measure steam flow?

Condensate Pot for Steam Flow Measurements TIPS AND TYPICAL INSTALLATIONS The concept of using impulse tubes (sensing lines) is basically the same whether working with steam flow instruments or liquid flow instruments. However, additional problems are introduced when measuring steam. The difference in density between the flowing

What’s the best way to install a condensate pot?

INSTALLATION TIPS 1. Use stainless steel tubing for the connection to the flanges or steam line. 2. Place the pot nearer the steam line or flange connection points. 3. Keep both the condenser and condensate chamber at the same level as the upper connection point. (An unequal level will cause significant error due to false reads.) 4.

What do seal pots and condensate drip pots do?

Condensate chambers, also known as seal pots and condensate drip pots, are welded pressure vessels that allow instruments and valves to be attached in line with routed tubing to allow for line sampling, elimination of fluid, and other processes.
