EXPANSION VESSEL CALIBRATION 14.1. EXPANSION VESSEL CALIBRATION H max (1) = 55 m Standard pre-load pressure value of the expansion vessel is 1,5bar/21,8PSI, whereas volume is 24 litres. Maximum pressure 6bar/87PSI. Calibration of the vessel must be regulated using the maximum level difference (H) of the user (see H = 12.25 m diagram) by using the following formula: p (calibration) [bar] = H [m] / 10.2 + 0.3. -
