Operating Principle
The electromagnetic flow meter is built on the principle of Faraday’s Law of Electromagnetic Induction. When a conductive fluid moves through a magnetic field, it generates a voltage signal that is directly proportional to the velocity of the flow. This induced voltage is collected by the measuring electrodes and transmitted to the amplifier. The system then determines the volumetric flow rate by combining the detected flow velocity with the pipe’s internal cross-sectional area.

Frequently Asked Questions (FAQs)
What is an Electromagnetic Flow Meter?
An Electromagnetic Flow Meter (also called a Magmeter) is a precision instrument used to measure the flow rate of conductive liquids. It works on Faraday’s Law of Electromagnetic Induction, where a voltage is induced when a conductive fluid passes through a magnetic field — this voltage is proportional to the fluid’s velocity and is used to calculate flow.
In which applications is an electromagnetic flow meter commonly used?
These meters are ideal for water treatment, chemicals, sewage, pharmaceutical plants, pulp & paper, steel, and other industries where conductive fluids are measured.
What are the standard output options available?
The flow meters provide 4–20 mA analog output, pulse output, and RS-485 Modbus digital communication for process control integration. Some models also support HART protocol for advanced diagnostics.
What is an electromagnetic flow meter and how does it work?
An electromagnetic flow meter operates based on Faraday’s law of electromagnetic induction. As a conductive fluid moves through a magnetic field, it induces a voltage proportional to flow velocity. Measuring electrodes capture this voltage, and the flow volume is calculated using the pipe’s cross-sectional area.
What type of fluids can be measured?
Electromagnetic Flow Meters measure any conductive liquid such as water, wastewater, slurries, acids, bases, chemicals, milk, fruit juices, or pharmaceuticals. Non-conductive fluids like oil, gas, or distilled water cannot be measured.
Do Electromagnetic Flow Meters require maintenance?
No, since there are no mechanical parts, maintenance is minimal. Periodic cleaning of electrodes and calibration checks ensure accuracy and reliability.
