For clean, non-turbulent air networks, hot-wire measurement is the most precise and sensitive solution. Throughout the ventilation network, our probes and their extension leads enable measurements in compliance with existing standards (NF X10-112, NF 12599, NF 16211, etc.).

Our hand-held devices feature an "Average" function to obtain a flow value that represents the entire airflow in the duct from several measurement points. This method ensures optimum measurement of the duct airflow.

L-shaped Pitot tube measurement enables reliable measurement in ducts where the air may be polluted, at high temperature, slightly turbulent, and up to a speed of 100 m/s. This measurement is made using a pressure sensor integrated into a manometer or multifunction device.

To compensate for any turbulence, our Class 210 and 310 devices feature a "measurement integrator" function to smooth out fluctuations. An averaging function also enables reliable determination of duct air velocity or airflow.

Sauermann manufactures DEBIMO wings with various measuring points positioned in accordance with NF X10-112 standards, ensuring efficient measurement averaging. This measurement can be compensated for temperature and atmospheric pressure, depending on the associated sensor model.

For highly sensitive, accurate measurements in non-turbulent flows up to 50°C, hot wire is recommended. For turbulent and polluted flows up to 210°C, DEBIMO wings provide a more suitable multi-point, averaged measurement.

Direct air velocity and airflow calibrations are carried out on our laboratories' large test benches, which offer state-of-the-art calibration reliability.
