Electromagnetic flow meters use the law of electromagnetic induction. When conductive fluid passes through a magnetic field, an induced voltage is proportional to the average velocity of the fluid.
This electromotive force is produced at the direction which is a right angle to the flow of the fluid and to the magnetic field. It is detected by the electrodes mounted in the middle of the measuring pipe, and the flow is calculated based on the detected electromotive force.

Electromotive Force (e) = Strength of magnetic field (B) × Average Velocity of Fluid (V) × Distance Between Electrodes (D)

Realizing our supreme technology of energy conservation, for the first time in the world, we succeeded to launch an electromagnetic water meter that can ensure ten years of continuous measurements even though it is driven by its built-in batteries.
Our electromagnetic water meters do not have moving parts in flow-pass, which eliminates pressure loss and provides excellent durability and higher resistance to the inclusion of foreign objects.
They can be installed flexibly, either in a perpendicular or parallel direction, and are capable of accurate measurement in a wide range of flow volume from small to large.

With the aim of further expanding the scope of applications, we continue to proceed with innovations in electromagnetic technologies: from water filled pipes to partially filled pipes, for lower flow rates, and for lower power consumption.
