Mesure des faibles débits de poudres et poussières
Parfaitement adapté pour contrôler et ajuster l’injection de réactif dans les lignes de traitement et de transport des fumées à très faible concentration de matière
Capteur électrodynamique pour la mesure de faibles débits de 0 à 100 kg/h.
Pour des diamètres de conduite jusqu’à 1m.
Idéalement utilisé dans les transports en phase diluée.
En chute libre avec une vitesse de chute d’au moins 2 m/s.
- Adapté aux très faibles concentrations
- Revêtement en céramique empêchant l’usure du capteur.

- Particularly good in pneumatic applications for material flow rates from a few g/h up to a few hundreds kg/h (depending on application)
- Very reliable for free-fall applications with a drop speed of at least 2 m/s (approx. 25 cm drop height)
- In cases where dust measuring instruments cannot cope and flow rate measuring instruments are overspecified
- The PicoFlow is perfectly suited for industrial applications especially in power generation or cement plants where it can be used to regulate or control additional reagent in flue gas treatment: injection of activated carbon, minsorb, lignite coke…

| The PicoFlow can be installed in metallic ducts and pipelines.
It should be installed as far as possible away from curves and other fittings such as valves and slides. The distance between the sensor rod and fittings in the duct should be at least three times the duct diameter in every flow direction. Non-metallic ducts must be cased with a metal sleeve, a metal foil or a tight-mesh metal grille over a length of at least five times the duct diameter. |
