Measure and control SA/RA flow rates at the AHU

Measure and Control OA Intake flow rates

Measure and control SA/RA flow rates at each “branch”.

Measure and control SA/RA flow rates into each zone on multi-pressure zone systems.

Monitor “bleed” airflow across critical pressure boundaries to verify pressurization and reset differentials if necessary.

Measure Exhaust flow rates if a.) rates are variable or b.) changes in fan performance with static pressure will significantly impact pressurization.
