Product Description

 DN3mm~DN3000mm RS485 Communication Electronic Magnetic Liquid Flow Meters

The Electromagnetic Flow Meter is a precision instrument used to measure the flow rate of conductive liquids, like water and slurries, based on Faraday's law of electromagnetic induction. It employs a magnetic field to induce voltage in the fluid, allowing for accurate and reliable flow measurements. Widely used in industries such as water treatment, chemicals, and food processing for efficient liquid monitoring.
