Dry leg calibration is nothing but the calibration of a DP tx in an closed tank.In a closed tank , the LP side is connected with the top of the tank and HP side is connected with the bottom of the tank to measure the height of the liquid column present in the tank.
Phigh = Pgas + S.H
Plow = Pgas
DP = Phigh - Plow = S>H
