Understanding SCFM, ACFM and ICFM measures of flow and what is needed to provide a solution
Volumetric flow measurements can be confusing, and some equipment manufacturers tend to be a little vague in order to reflect positively on the performance of their equipment. The first reason for the confusion is the simple fact that gases are compressible. As such, variations in pressure, temperature, and humidity significantly change the volume and density properties of the gas. Additionally, there are many variations in the “standard” definitions for the different flow rate measurements. It can all seem pretty confusing.
