2. Measure Airflow Accurately
What is an AFMS
Accurately measures airflow within a duct
Measure Exhaust, Mixed but most commonly Outside Air
Outputs a signal proportional to CFM
Validates the Building is meeting the minimum outdoor air requirements of ASHRAE Standard 62 or California Title 24 by providing accurate monitoring and control of outside air
Several LEED Credits available under EA and IEQ
