Mass flow versus volume flow in gas flow calibration (769.59 KB)

Mass flow is the movement of a quantity of material through a conveyance per quantity of time. SI units of measure for this parameter are kg/ sec. Conversions of kg/sec to a variety of other mass flow units are possible, such as g/s and mole/s.

Volume flow is the measurement of the volume of gas through a conveyance per quantity of time. SI units of measure for this parameter are m3/s. Other units used for volume flow are lpm, cfm, ccm. Volume flow is sometimes referred to as actual flow, and units of acfm, alm are common.
