All Victor flow meters are back pressure compensated to ensure accurate readings at all times, even if line restrictions are present. All flow meters are calibrated to operate at 25 PSIG inlet pressure to minimize surge, except the FM 200 which is calibrated to operate at 80 psig. Not designed for cylinder use. Do not exceed calibrated inlet pressure
