What is the difference between mass flow and volumetric flow?

Volumetric flow describes gas volume under defined conditions, while mass flow measures the actual gas quantity. Mass flow is often better for accurate monitoring and control.

In compressed air and gas systems, volumetric flow measures how much gas volume passes a point over time, standardized to fixed temperature and pressure conditions.

Mass flow measures the actual mass of the gas moving through the system and is not affected by changes in temperature, pressure, or gas composition. Because it reflects true gas quantity, mass flow is more accurate for process control and energy monitoring.
