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 - ...
Magnetic flow meters (magmeters) are indispensable tools for measuring the flow of conductive liquids in industries ranging from water treatment to pharmaceutical production. But one critical question often arises: What is the minimum conductivity required for these devices to work accurately? In this article, we’ll dive into the science behind magmeters, explain why conductivity matters, and explore advanced solutions like the RBEF8C Low Conductivity Electromagnetic Flow Meter that push the boundaries of traditional limits. How Magnetic Flow Meters Work: The Role of Conductivity Magnetic flow meters operate on Faraday’s Law of Electromagnetic Induction. Here’s the basic principle: 1. When a conductive fluid flows through a magnetic field generated by the meter’s coils, it induces a voltage proportional to the flow velocity. 2. Electrodes mounted on the pipe wall detect this voltage, which is then converted into a flow rate. K...
