The 4800 Electromagnetic Flowmeter is a high-accuracy device designed for precise measurement of liquid flow in pipes and channels. Using Faraday’s law of electromagnetic induction, it measures the velocity of conductive fluids without any moving parts, ensuring reliable performance and minimal maintenance.
