Control Engineering | Density compensation for steam drum

Sep 02, 2014 · Saturated (not superheated) steam at 1310 PSIG is 5% the density of 100°F water. For example, if a drum were full of 580°F water up to the top tap 50" above a bottom tap, it would register over 13" of DP, instead of the 0" DP it would read if the densities were the same. If the water is at the operating level 18" above the lower tap, the
