WebApr 19, 2003 · David W Spitzer. Mar 23, 2003. #4. Scott, The differential pressure transmitter measures the flow in scfm or acfm (see your flow element calculations) based upon the operating pressure and temperature that were used in the flow element calculations. Flow element testing may (and likely was) performed at other conditions. Actual cubic feet per minute (ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never … See more Standard cubic feet per minute (SCFM) is a volumetric flow-rate corrected to a set of "standardized" conditions of pressure, temperature, and relative humidity. The standard conditions are often defined as 14.7 psia, … See more Ratings found in centrifugal fan performance tables and curves are based on standard cubic feet per minute (SCFM). Fan manufacturers define standard air as clean, dry air with a density of 0.075 pounds mass per cubic foot, with the atmospheric pressure See more • Cubic feet per minute (CFM) • Standard cubic feet per minute (SCFM) • Standard cubic foot (SCF) See more Normal cubic feet per minute (NCFM) refers to air at normal conditions, such as 14.7 psia, 68°F, 36% relative humidity. However, there is not an agreed upon definition for what … See more Free air delivery (FAD) indicates delivered air, referred to as "free air", at inlet conditions. See more The centrifugal fan performance tables provide the fan revolutions per minute (RPM) and brake horsepower requirements for the given CFM and static pressure at standard air density (0.075 pounds per cubic foot).
