1. Electromagnetic flow meter instruments Working principle

Electromagnetic flow meters operate based on Faraday's law of electromagnetic induction. When a conductive liquid flows in a magnetic field, it cuts the magnetic lines of force, thereby generating an induced electromotive force on the measuring electrodes. This induced electromotive force is proportional to the liquid's flow velocity. By measuring the magnitude of the induced electromotive force, the liquid's flow rate can be accurately calculated.

The measuring tube of an electromagnetic flow meter typically contains no components that obstruct fluid flow, enabling it to measure the flow rate of various corrosive and conductive liquids, including oil, natural gas, and chemical solutions. Furthermore, electromagnetic flow meters boast high measurement accuracy and stability, unaffected by factors such as fluid temperature, pressure, density, and viscosity, providing long-term reliable measurement data.
