Greenheck airflow measuring products are available with either differential pressure based technology or thermal dispersion technology. 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 or pressure drop across a calibrated orifice (fan inlet venturi). Thermal dispersion technology utilizes an array of thermal dispersion nodes positioned across the face of a duct or opening.
