Gases can be compressed. Consequently, pressure and temperature (and the kind of gas) have a direct impact on the display of the flow meter. We therefore calibrate the unit for the specific customer conditions that have been provided at the time of the order.
The flow values indicated on the flow table or on the measuring tube always refer to the depressurised state at 0°C and 1013.25 mbar abs. A different reference temperature or reference pressure is not possible.
If the temperature and pressure varies a lot we recommend you us a digital red-y compact flowmeter unit which automatically compensates for changes in pressure and temperature.
