CO2 (0 °C)22Nm3/hType 2:500mbar
N (0 °C)50Nm3/hType 3:1bar

Caution: If the pressure will exceed the above-mentioned set pressure, the safety valve will open. However, if the flow rate from the gas source exceeds the above-mentioned max. flow rate, the valve would not be able to vent the meter quickly enough.

This would built-up a pressure inside of the meter and may destroy the gas meter despite of the opened valve!
