Maintaining flow measurement reliability
The flow sensors in the ducts of dedusting systems use very reliable "Pitot" technology, but they are naturally subject to clogging. A cleaning solution exists to maintain the reliability of their measurements.
Dedusting systems are essential for evacuating particles and pollutants, and require continuous airflow measurement, the accuracy of which must be maintained to ensure optimum efficiency of the building's aeraulic system. However, this measurement is disrupted by the inevitable clogging of flow sensors by dust.

Continuous Monitoring
The best monitoring solution is based on a transmitter equipped with a self-calibrating pressure sensor and a stainless steel Pitot S probe, together with a dust collection box that automatically blows away dust to unclog the measuring holes.
The DEBIMO wings solution has the advantage of providing a multi-point measurement that gives a meaningful average of the entire duct cross-section. For maximum durability, these aluminium wings have an optional ECTFE treatment for solvent resistance.
BP 100
Le coffret de dépoussiérage BP100, piloté par des capteurs de pression C310 ou CP210-R, permet de dépoussiérer les tubes de Pitot ou les ailes de mesure de débit montés en poste fixe sans faire de démontage. Le principe consiste à souffler de l’air comprimé du réseau (5 à 7 bars) en sens inverse dans les éléments de mesure afin d’évacuer ou de décolmater les poussières qui obstruent les orifices des prises de pression. Le coffret BP100 contient des électrovannes qui permettent d’isoler le capteur de pression avant l’admission d’air comprimé et d’arrêter l’air comprimé avant de rétablir le circuit de pression jusqu’au capteur. Ce dispositif permet de préserver le bon fonctionnement des capteurs de pression différentielle.
CP 210-R
The CP 210-R measures the differential pressure of air (and neutral gases), and is ideal for use in industrial and pharmaceutical applications.
Spot measurements
Spot measurements
Spot measurements are used to check the condition of the airflow network and its dust collection system, to ensure that airflow is guaranteed at different points in the ducts. They are used for periodic maintenance and repair operations.
A good portable measuring device can also be connected to Pitot S or DEBIMO probes installed in ducts to check that they are working properly. Their calibration must be certified to provide accurate measurements for comparison with those of fixed transmitters.
MP 210
Kimo’s MP 210 micromanometer measures pressure, air velocity, airflow, temperature, tachometry, gas leak and carbon monoxide (up to 6 simultaneous measurements).
AMI 310
Kimo’s AMI 310 measures simultaneous parameters including pressure, temperature (Pt100 and thermocouple), humidity, air quality (CO/CO2), air velocity, airflow (vane probes and hotwire), and tachometry.
