Magnetic Flow Meter Troubleshooting: Simple Fixes for Common Problems
Frustrated with your mag meter acting up? Let’s walk through quick diagnostics before calling the technician. For basic magnetic flow meter troubleshooting: Check power supply (10-36V DC), verify full pipe (no air gaps), inspect electrodes (clean with vinegar if coated), ensure proper grounding (1-ohm resistance to earth), and confirm fluid conductivity (>5 μS/cm). Most issues […]
Magnetic Flow Meter Pressure Drop: What You Need to Know
Worried about pressure loss in your pipeline? Let’s clear up the confusion around magnetic flow meters. Magnetic flow meters (mag meters) have no moving parts and create minimal pressure drop—typically less than 0.1 bar (1.5 psi) under normal flow conditions. Unlike restrictive devices (orifice plates, venturis), they maintain near-full pipe diameter, preserving system pressure efficiently. […]
Magnetic Flow Meter Piping Requirements: Complete Installation Guide
Installing a magnetic flow meter correctly ensures accurate, long-lasting performance. Magnetic flow meters require specific piping conditions: 1) Full-pipe flow (except special non-full pipe models), 2) 10 pipe diameters straight run upstream (5D downstream), 3) Proper grounding, 4) Conductive fluids (>5 μS/cm), and 5) Correct pipe size matching the meter’s bore diameter. Proper Magnetic Flow […]
Magnetic Flow Meter Operating Principle: Complete Guide
Magnetic flow meters revolutionized industrial flow measurement since their introduction in the 1950s. Understanding their working principle is essential for proper selection and operation. Magnetic flow meters operate on Faraday’s Law of Electromagnetic Induction – when a conductive fluid flows through a magnetic field, it generates a voltage proportional to flow velocity (typically 0.1-10 m/s […]
Magnetic Flow Meter K-Factor: Complete Explanation
Understanding the K-factor is essential for accurate flow measurement and calibration in industrial applications. The K-factor in magnetic flow meters represents the number of electrical pulses generated per unit volume of fluid flow (typically pulses/gallon or pulses/liter), serving as the critical calibration constant that converts the meter’s raw signal into actual flow rate measurements. Magnetic […]
