Electromagnetic flow meter
Water & Wastewater Management: Used in municipal networks for drinking water distribution, sewage monitoring, and leak detection.
Chemical & Corrosive Handling: Ideal for measuring aggressive acids, alkalis, and chemical solutions because the internal lining (like PTFE) resists corrosion.
Food & Beverage Production: Employed to measure liquids like milk, juice, and syrups in a hygienic, non-contaminating way that meets food safety standards.
Mining & Slurry Transport: Capable of measuring abrasive mixtures, such as ore pulp or tailings, without the mechanical wear that ruins traditional meters.
Pharmaceutical Manufacturing: Used for the precise dosing and blending of liquid ingredients and sterile solutions to ensure strict quality control.
Magnetic Field Creation: Two electromagnetic coils outside the flow tube generate a constant magnetic field that passes through the pipe’s cross-section.
Conductive Flow: As a conductive liquid (like water) flows through this field, it acts as a moving conductor cutting through magnetic flux lines.
Voltage Induction: This movement induces a small electrical voltage within the liquid that is directly proportional to its flow velocity.
Signal Detection: Two electrodes mounted on the inner walls of the pipe detect this induced voltage and send the signal to a transmitter.
