The electromagnetic flowmeter measures the volumetric flow of conductive liquids based on Faraday’s Law of Electromagnetic Induction, combining principles of fluid mechanics and electromagnetism. An electromotive force is induced at both ends of a conductor when it cuts magnetic‑field lines while moving through a magnetic field.

The electromagnetic flowmeter consists of two parts: a sensor and a converter. As an inductive instrument for conductive media, it measures volumetric flow of liquids with conductivity above 5 μS/cm. Besides ordinary conductive liquids, it is also suitable for strongly corrosive fluids such as strong acids and alkalis, as well as homogeneous liquid‑solid two‑phase suspensions including mud, ore slurry and paper pulp.

High‑quality and reliable components are adopted with optimized structural design to achieve improved and more evenly distributed magnetic fields. A zinc‑spraying process is applied to provide long‑term surface protection for the flowmeter tube body even under harsh operating conditions, delivering excellent anti‑corrosion performance.

It is widely used for flow measurement in petroleum, chemical, metallurgical, textile, papermaking, environmental‑protection, food and other industrial sectors, as well as municipal administration, water conservancy construction and river dredging projects.

Features
