A process used to determine the differential pressure present WITHIN a liquid-filled space.The formula for determining the differential pressure within a wet leg design is: d/p = h (SG)

Where: d/p = differential pressure, h = HEIGHT of liquid present, and SG = specific gravity

When the process vapors CONDENSE at normal ambient temperatures or are corrosive, this reference leg can be filled to form a wet leg. If the process CONDENSATE is corrosive, unstable, or undesirable to use to fill the wet leg, this reference leg can be filled with an inert liquid.
