Electromagnetic flow meters (or magmeters) are a type of velocity or volumetric flow meter that operate pursuant to Faraday's law of electromagnetic induction - which states that a voltage will be induced when a conductor moves through a magnetic field. Magmeters can detect the flow rate of conductive fluids only.

Magnetic flow meters will generally deliver a turndown ratio in the realm of 40:1. This is higher than many other technologies. But it is generally true that the technology that offers the best turndown ratio is the ultrasonic technology, like our DUK Inline Ultrasonic Flow Meter, with a turndown ratio of 250:1.

A magnetic flow meter (mag meter, electromagnetic flow meter) is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines. The physical principle at work is electromagnetic induction. The

Electromagnetic (mag) flow meters are volumetric flow meters that do not have any moving parts to wear down, reducing the need for maintenance or

Additionally, some of the process fluids listed in this guide do not meet the minimum conductivity requirements for a magnetic flow meter. However, they are listed to aid the user in instances where there may be trace amounts contained in the process fluid. Figure 1: Cutaway view of a magnetic flow meter A. Liner B. Electrodes Contents

Electromagnetic flow meters (also called mag meters or magnetic flow meters), are volumetric flow meters that use electromagnetic induction to measure liquid velocity. This method of measurement is highly accurate at measuring water-based fluids as they pass through a pipe. Mag flow meters do not have any moving parts, so there is minimal need

Principle of Magnetic Flow Meter Based on Faraday's Law. Magnetic flow meters works based on Faraday's Law of Electromagnetic Induction. According to this principle, when a conductive medium passes through a magnetic field B, a voltage E is generated which is proportional to the velocity v of the medium, the density of the magnetic field and the length of the conductor.

Magnetic flow meters, also known as electromagnetic flowmeter and mag meters, usually used for flow measurement of conductive liquids.

Electromagnetic Flowmeter Measurement Principle. The electromagnetic flowmeter uses Faraday's Law of electromagnetic induction to measure the process flow.

Electromagnetic meters operate under Faraday's Law of Electromagnetic Induction to measure liquid velocity. The law states that a conductor moving through a
