LDG Electromagnetic Flowmeter

An electromagnetic flowmeter has two main components - the sensor and the converter. It works by utilizing Faraday's law of electromagnetic induction to measure the flow of conductive liquids. This device is widely used in various industries such as metallurgy, chemical, paper and pulp, environmental protection, petroleum, textile, food and beverage, municipal management, and water conservancy construction.
The electrodes generate a magnetic field that induces a voltage in the conductive liquid. Meanwhile. The converter converts the voltage signal into a flow rate. As a result. The electromagnetic flowmeter provides highly accurate and reliable readings, enabling precise measurements in different industrial applications.
