Electromagnetic Flow Meters

Electromagnetic flow meters manage critical flow applications to improve accuracy, decrease system maintenance and meet the demands of challenging liquid conditions. This volumetric flow meter does not have any moving parts and is ideal for wastewater applications or any dirty liquid that is conductive or water-based. 

Electromagnetic Flow Meters

Improve Accuracy. Decrease System Maintenance.

Electromagnetic meters are a leading choice to deliver the performance and precision your applications require.

  • Minimal Maintenance. Has no moving parts or flow obstructions, which virtually eliminates maintenance and pressure drops.
  • Impressive Accuracy. Provides accuracy readings up to +0.20% of the measured value.
  • Wide Turndown Range. Features a wide turndown ratio up to 400:1, providing wide flow range capabilities across a variety of applications.

Measuring Principle
Measuring Principle

Electromagnetic meters operate under Faraday’s Law of Electromagnetic Induction to measure liquid velocity. The law states that a conductor moving through a magnetic field produces an electrical signal within the conductor, which is directly proportional to the velocity of the water moving through the field.

How It Measures
How It Measures

As a conductive fluid—like water—flows through the magnetic field, a voltage is induced across the two measuring electrodes. The resulting voltage magnitude is directly proportional to the average velocity of the fluid. The induced voltage is then amplified and digitally processed to produce an accurate digital or analog signal. This signal can then be used to indicate flow rate or totalization of fluid volume, or to communicate or interface with another piece of equipment.
