        Differential Pressure

        Airflow station with control damper

        Differential pressure based airflow measuring products use an array of air pressure pick-ups to compare the total pressure going through the airflow station with the static pressure in the station. The AMD series combines the function of an accurate airflow measuring station and low leakage control damper into one compact assembly.
