Electronic COMETER

FEATURES:

The Electronic Cometer is a transducer that calculates and displays the airflow delivered by a fan. The determination is made by measuring the piezometer ring differential pressure. It measures up to 10 WG SP.
the measuring system can achieve an

accuracy of ± 5%.

BENEFITS:

The same Electronic Cometer can equip all double double inlet and plug fans since the formulas are pre-programmed and the coefficients can be set during installation.
Electronic Cometer installation is very easy on air handling units fans.
