Media 7 Differential Pressure Meter
(All pressure in bar (gauge); all errors and deviations are specified in % of the adjusted measuring span)
Mounting orientation Upright with display facing sideways
Principle of operation The differential pressure at the diaphragm is converted into an electric
signal by the AMR system.
Pressure rating PN 60, overloadable on one side up to 60 bar
Oxygen: PN 50, overloadable on one side within the adjusted system
pressure
Characteristic Differential pressure proportional to the tank geometry
Deviation from terminal-based linearity <±1.6 % (including hysteresis)
Sensitivity ≤0.25 % or <±0.5 % depending on measuring span selected
Effect of static pressure <0.03 %/1 bar
