Abstract
Airflow calibration systems are provided that are configured to be received in a duct of a heating, ventilating and air conditioning (HVAC) system. The air flow calibration systems include a housing including an air flow grid; and at least one pressure sensing cell positioned in the housing, the at least one cell being configured such that air flows through the at least one cell when the airflow calibration system is positioned in the duct of the HVAC system. The airflow calibration system is configured to be temporarily installed in the duct of the HVAC system to calibrate the HVAC system upon completion of the HVAC system or to recalibrate the HVAC system after a period of time.
