DN300 Digital Output Modbus Electromagnetic Flow Meter for Water
The Electromagnetic Flow Meter is a precision instrument used to measure the flow rate of conductive liquids like water and chemicals. It operates on Faraday's law of electromagnetic induction, generating a voltage proportional to the fluid velocity. This accurate and durable meter is widely employed in industrial processes, water treatment, and environmental monitoring for efficient flow measurement.
