Electromagnetic Flow Measurement: Unveiling the Basics

At its core, electromagnetic flow measurement harnesses the power of electromagnetism to gauge the flow rate of conductive fluids. Unlike conventional methods, this technique excels in measuring even corrosive and abrasive liquids without compromising accuracy. Employing Faraday’s law of electromagnetic induction, it provides a non-intrusive, obstruction-free solution for monitoring fluid movement.

How Does Electromagnetic Flow Measurement Work?

The functioning of electromagnetic flow measurement is ingeniously simple. An electromagnetic flow meter consists of a pipe through which the fluid flows. Embedded within the pipe are electrodes that create a magnetic field perpendicular to the fluid’s flow. As the conductive fluid passes through this magnetic field, it generates a voltage proportional to its velocity. This voltage is then measured and converted into an accurate flow rate reading.
