Air flows through the Measurement Unit which is installed tightly into the ductwork. Airflow in a duct creates a pressure difference between the front and rear probes. The corresponding airflow rate can be defined by measuring the pressure difference sensed by the averaging probes.
The casing of the measurement unit shall be made of galvanised steel.
The measurement probe pipes shall be made of aluminium.
Measurement based on differential pressure in measurement probe created by airflow
Very accurate measurement, inaccuracy less than 10%
Measurement probes can be removed for cleaning
Galvanised steel design
Classification of casing leakage EN 1751 class C
Installation independent of airflow direction
