Gas Flow Calculation
Flowmeters are calibrated for a specific gas (e.g. nitrogen
for the RTA). To calculate the flow rate of another gas,
multiply the reading by the ratio of the conversion factor or the
desired gas to the conversion factor for the calibration gas.
For example on the RTA (calibrated for nitrogen), if the indication
is 200 ml/min and the gas is Argon, the actual flow rate is
200 * 1.443=288 ml/min.
