Flo-Dar : Une Solution Fiable pour la Mesure de Débit Sans Contact dans le Traitement de l'Eau et de l'Environnement
Introduction:
Dans le domaine du traitement de l'eau et de l'environnement, la mesure précise du débit est cruciale pour optimiser les processus, garantir la conformité et protéger l'environnement. Les débitmètres traditionnels nécessitent souvent des installations intrusives, pouvant perturber le trajet du flux et affecter la précision de la mesure. Entrez Flo-Dar, un débitmètre de surface/vitesse sans contact développé par Marsh-McBirney, Inc., qui offre une solution fiable et polyvalente pour mesurer le débit dans diverses applications difficiles.
Qu'est-ce que Flo-Dar ?
Flo-Dar est un débitmètre électromagnétique sans contact qui utilise le principe de l'effet Faraday pour mesurer la vitesse d'écoulement des fluides conducteurs. Il se compose de deux composants principaux :
- Générateur de champ magnétique : Un champ magnétique est généré autour du tuyau transportant le fluide.
- Capteur d'électrode : Des électrodes placées à l'extérieur du tuyau mesurent la tension induite par le mouvement du fluide à travers le champ magnétique.
Avantages de Flo-Dar dans le traitement de l'eau et de l'environnement :
Installation non intrusive : Flo-Dar ne nécessite aucune insertion dans le trajet du flux, minimisant le temps d'installation, les perturbations et le risque de contamination du fluide.

Large plage de débit : Flo-Dar peut gérer divers débits, des applications à faible débit comme l'irrigation goutte à goutte aux applications à haut débit comme les stations d'épuration des eaux usées.
Résistance à l'encrassement et au colmatage : Contrairement aux débitmètres traditionnels avec des pièces mobiles, Flo-Dar n'est pas sujet au colmatage ou à l'encrassement, assurant une fiabilité à long terme.
Convient aux conditions difficiles : Flo-Dar peut résister à des environnements difficiles comme les fluides corrosifs, les pressions élevées et les températures variables, ce qui le rend idéal pour les applications exigeantes de traitement de l'eau.
Applications dans le traitement de l'eau et de l'environnement :
- Traitement des eaux usées : Mesure du débit dans les flux d'arrivée, de sortie et de processus pour un traitement efficace et une surveillance de la conformité.
