## [Duct airflow control](/en-AU/solutions/duct-airflow-control) ![AHU](/sites/default/files/entityone_paragraphs/images/SOLUTION_MAITRISE_DU_DEBIT_D%27AIR_468x468.png) ## Reliable measurements for optimum HVAC management Duct measurement is a highly complex process, since its effectiveness depends on the many different configurations of the ductwork. Good measurement is essential to ensure efficient air distribution in a building and the comfort of its occupants. Mapping cross-sections, taking into account turbulent areas, determining the right measurement locations and taking multi-point readings (exploring velocity fields)... All these complex methods require the use of portable and fixed measuring instruments with different probe types. ## Parameters to be monitored - **Airflow** - **Velocity** - **Temperature** - **Pressure** Hot wire measurements ## Hot wire measurements 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.

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.

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.
