Magnetic flow meters (magmeters) are widely used for measuring conductive liquids in industries like water treatment, chemical processing, and food production. However, their accuracy and longevity depend heavily on meeting specific requirements and proper installation. Here ’ s what you need to know: Key Requirements for Magnetic Flow Meters 1. Fluid Conductivity - Minimum Conductivity: The liquid must have a conductivity of ≥ 1 µS/cm (varies by model). Pure water or non-conductive fluids (e.g., oils) are unsuitable. 2. Full Pipe Flow - Ensure the pipe is 100% full during operation. Air bubbles or partially filled pipes cause measurement errors. 3. Pipe Material - Use non-magnetic pipes (e.g., PVC, stainless steel, or lined pipes). Magnetic materials (e.g., carbon steel) disrupt the meter ’ s magnetic field. 4. Grounding - ...
