MFC are calibrated with Air at 5 barg inlet, 0 barg outlet, 20°C. Conversion factors (Kfactors) are applied for other gases: 

For N2 and O2, accuracy and repeatibility unchanged. For Ar and CO2 , repeatibility <1%, accuracy +/-10%. For better accuracy, needs to be calibrated with specific gas on request. When switching from one gas to another, it is common practice to flush before use with new gas.
