What conditions (pressure and temperature) are the devices designed for?

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. Please note that 1 bar deviation from these values can already mean an error of 40%.
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.
