While fan inlet airflow measurement placement eliminates some design issues for the engineer troublesome installation issues e g access to the reverse side of dual inlet fans arise as do fan sound and fan performance issues.
At kele we make it easy to find the right flow product.
Kele outdoor airflow measuring systems.
Ruskin s efams electronic fan inlet air measurement station utilizes thermal dispersion technology combined with low pressure drop aerodynamic sensors to measure the airflow at the highest velocity point in the system.
This lower pressure drop equates to lower cost of operation over the life of the building when compared to other fan inlet devices.

The sure aire system measures airflow without the use of traditional restricting flow measuring probes.
The result is accurate.
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.
