How Does a Flow Hood Measure Airflow

Flow hoods have been used for many years in the HVAC industry as a method of measuring the air flows at registers. … The register flows in residential systems are used to determine if individual rooms are getting the correct airflow, and in estimates of total air handler flow and duct air leakage.

How do you calculate cfm of air flow?

CFM = (fpm * area), where fpm is the feet per minute. To find the cubic feet per minute, substitute the FPM value with the area after the area is squared.
