10.a.2 - Working from a airflow coefficient
With this coefficient, you can calculate the airflow from the pressure. This coefficient is given by the manufacturer of the
devices supplied with pressure connections (+ and -). From the square root of the pressure measured (Delta P),and from this
coefficient, you get the airflow.
Airflow = C x Pressure

Function only available for the pressure transmitter: CP 200 + SQR option. In this calculation mode, you
have no access to reading of air velocity. If you activate this calculation mode and also a channel in
air velocity, the transmitter will display an error code “4”.
