The Electromagnetic Flow Meter operates based on Faraday's law of electromagnetic induction. When a conductive fluid, such as water or certain chemical solutions, flows through a magnetic field generated by the meter, an electromotive force is induced. This induced voltage is proportional to the flow velocity of the fluid. By measuring this voltage and knowing the cross - sectional area of the pipe, the flow rate can be accurately determined. Smart Electromagnetic Flow Meters are known for their high accuracy, typically within ±0.2% to ±1% of the measured value. They have a wide flow range and can handle various flow conditions, including high - velocity and low - viscosity fluids. Inline electromagnetic flow meters are resistant to fouling and corrosion, making them suitable for use in harsh industrial environments. Applications include wastewater treatment, food and beverage production, and pharmaceutical manufacturing, where accurate and reliable flow measurement is crucial for process control and quality assurance.
