Conversion Table

The relationship between water vapor concentration and other conversion factors to express the con-
centration of water vapor in a gas is:
Parts per Million by Volume x

*M Wt = Molecular weight of sample gas
Flowmeter Correction Factors
Divide desired flow rate by the correction factors to obtain approximate flowmeter setting.
If a more accurate flowmeter setting or a setting for a gas not listed is desired, use the Bubble-O-Meter
tailed in Appendix A.
