Electromagnetic flow meter is one of the most popular flow meters. Flange type electromagnetic flow meter has been used for more than 50 years worldwide. It is widely used for all conductive liquids in every industry, such as water, acid, alkali, milk, slurry etc.

The electromagnetic flow meter consists of a non-conductive pipe lined with a conductive material, typically made of metal. The meter contains coils or electrodes positioned opposite each other on the pipe’s inner walls. A magnetic field is then generated by passing a current through these coils, creating a measurable voltage across the fluid. The induced voltage, or EMF, is directly proportional to the fluid’s velocity, allowing the flow meter to accurately determine the flow rate. Importantly, this principle remains effective regardless of the fluid’s conductivity, making electromagnetic flow meters suitable for a wide range of applications, including water, wastewater, and various industrial processes.
