Electromagnetic flow meter As a flow measurement instrument widely used in industrial fields, it is favored by all walks of life for its high precision, high reliability, and wide applicability. In order to gain a deeper understanding Electromagnetic flow meter of the production process and the secrets of its precise measurement, we visited a well-known electromagnetic flow meter manufacturer for a field visit.

I. Basic principles of electromagnetic flow meters

Electromagnetic flow meters are designed based on Faraday's law of electromagnetic induction. When a conductive liquid flows in a magnetic field, an induced electromotive force will be generated in the liquid, and this electromotive force is proportional to the flow velocity of the liquid. By measuring the induced electromotive force, the flow velocity of the liquid can be accurately calculated, and then the flow rate can be obtained. Its core components include a sensor and a converter. The sensor is responsible for sensing the electromotive force, and the converter converts the electromotive force into readable flow data.
