Overview
Magnetic flow meters, or magmeters, are advanced devices used to measure the flow rate of conductive fluids. By utilizing Faraday’s law of electromagnetic induction, these meters provide accurate and reliable measurements without any moving parts, making them ideal for handling corrosive, viscous, or slurry-based fluids. Industries such as water treatment, chemical processing, and food and beverage widely use magnetic flow meters.
