UniMag : Un Outil Puissant pour le Traitement de l'Environnement et de l'Eau
Dans le domaine du traitement de l'environnement et de l'eau, une mesure de débit précise et fiable est primordiale. De la surveillance du rejet des eaux usées au contrôle du dosage des produits chimiques, connaître le volume de fluide traversant un système est crucial. UniMag, une technologie de débitmètre magnétique non intrusif, est devenu un outil puissant pour ces applications, en particulier lorsqu'il est utilisé en conjonction avec les débitmètres à tuyau fermé d'Isco, Inc.
Qu'est-ce que UniMag ?
UniMag signifie "Universel Magnétique", un terme descriptif pour un type de débitmètre qui exploite les principes de l'induction électromagnétique. Cette technologie fonctionne sans obstructions physiques dans le tuyau, ce qui la rend particulièrement adaptée aux environnements difficiles avec des fluides abrasifs, une viscosité élevée ou une teneur en solides.
Fonctionnement de UniMag :
Les débitmètres UniMag fonctionnent en générant un champ magnétique autour du tuyau. Lorsqu'un fluide conducteur traverse ce champ, un courant électrique est induit dans le fluide. L'amplitude de ce courant est directement proportionnelle au débit. Cela permet une mesure de débit précise et non intrusive sans avoir besoin de chutes de pression ou de restrictions communément associées à d'autres types de débitmètres.
Avantages de la technologie UniMag :
- Non intrusif : Les débitmètres UniMag sont installés à l'extérieur du tuyau, éliminant le besoin de capteurs intrusifs qui peuvent perturber le débit ou se colmater par des particules.
- Haute précision : La technologie UniMag offre une haute précision dans la mesure du débit, même à faibles débits et dans des environnements difficiles.
- Faible maintenance : Les débitmètres UniMag sont pratiquement sans entretien, nécessitant un étalonnage et un nettoyage minimaux.
- Convient à divers fluides : La technologie UniMag est compatible avec une large gamme de fluides conducteurs, y compris l'eau, les eaux usées, les produits chimiques et les boues.

Chapter 1: Techniques
UniMag: A Non-Intrusive Flow Measurement Technology
Electromagnetic Induction Principle:
UniMag flow meters utilize the principle of electromagnetic induction to measure flow. This technique operates without physical obstructions within the pipe, making it ideal for challenging environments with abrasive fluids, high viscosity, or solids content.
How it Works:
- Magnetic Field Generation: A magnetic field is generated around the pipe by the flow meter.
- Induced Electric Current: When a conductive fluid flows through this magnetic field, an electric current is induced within the fluid.
- Current Measurement: The magnitude of this induced current is directly proportional to the flow rate. This current is then measured by the flow meter.
- Flow Rate Calculation: The flow meter calculates the flow rate using the measured current and other known factors (e.g., pipe diameter, fluid conductivity).
Advantages of UniMag Technology:
- Non-intrusive: No physical obstructions within the pipe, reducing the risk of fouling or damage.
- High Accuracy: Provides accurate flow measurements, even at low flow rates and in challenging environments.
- Minimal Maintenance: Requires little to no calibration or cleaning, reducing downtime and operational costs.
- Wide Fluid Compatibility: Suitable for a variety of conductive fluids, including water, wastewater, chemicals, and slurries.
Limitations of UniMag Technology:
- Conductivity Requirement: The fluid must be electrically conductive for the technology to function.
- Pipe Material: The pipe material should be non-magnetic or minimally magnetic to prevent interference with the magnetic field.
- Flow Velocity: UniMag technology may be less accurate at very low flow velocities.
