Explore electromagnetic flow meters and mag meters. Learn about industrial flow sensors, measurement principles, and technical specifications for liquid flow.

The beauty of electromagnetic flow meters is that because there are no moving parts, you get an insignificant pressure drop and high reliability across extreme temperatures. It’s a perfect blend of high-level physics and rugged engineering that allows for precise measurement without anything in the pipe to wear out or clog.

Electromagnetic flow meters, often referred to as mag meters, are designed for precise liquid flow measurement in various industrial applications. These industrial flow sensors are known for their ability to handle conductive fluids without moving parts, which minimizes pressure drop and maintenance requirements. Key features typically include high accuracy, wide turndown ratios, and compatibility with corrosive or abrasive liquids, making them a versatile choice for modern flow measurement technology.
The technology is based on Faraday's Law of Electromagnetic Induction. When a conductive liquid flows through a magnetic field generated by the meter, it creates a voltage proportional to the velocity of the fluid. This principle allows the electromagnetic flowmeter to provide highly accurate readings for liquid flow measurement. Because the measurement is independent of fluid density, viscosity, and pressure, it remains a reliable standard for industrial process control.
Mag meters are specifically designed for liquid flow measurement of conductive fluids. This includes a wide range of substances such as water, wastewater, acids, bases, and slurries commonly found in industrial environments. Since the measurement principle relies on electrical conductivity, these electromagnetic flow meters are not suitable for gases or non-conductive hydrocarbons like oil, but they excel in demanding chemical and municipal water applications.
