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

CONTINUOUS MONITORING
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.

PITOT TUBE MEASUREMENTS
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.

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.

    Si-PRO-V-300

    Interchangeable hotwire probe for air velocity and temperature measurements.
    Stainless steel body length 267 mm (10.51''), Ø 8 mm (0.31'').
    Thanks to its design, it minimises the impact of the angle of the airflow on the measurements.
    Main applications: laminar flow monitoring in clean rooms, isolators, glove boxes, fume hoods, isolation cabinets, pharma/cosmetic and semiconductors manufacturing facilities.
    Si-ACC-RVP probe cable for connection to class 320 transmitters is needed.

    Indoor air quality matters in data centres too!

    The number of data centres is increasing at an unprecedented rate as the world shifts to a digital-led economy. These server farms are also becoming ever bigger in size in order to keep up with the rapidly growing volume of data that needs to be stored, transferred and shared online. As the nerve centres of the web, data centres consume vast quantities of energy. They also generate a huge amount of heat, which can cause damage to components if left unchecked.
