EMF Magnetic Flowmeter

Electromagnetic flowmeter is composed of sensor and converter. It works based on Faraday’s law of electromagnetic induction and is used for conductive fluid. It can be used to measure the conductivity of acid, alkali, salt solution, pulp, wastewater and other conductive media, but the medium can not contain a large number of ferromagnetic materials and bubbles. It is widely used in the flow measurement of metallurgy, chemical industry, pharmaceutical industry, papermaking, environmental protection, petroleum, light textile, food and other industries, municipal management, water conservancy construction and other fields.


√ Measurable flow: 2L/h

√ Accuracy: 0.2%

√ GPRS, Bluetooth wireless transmission

√ MODBUS, HART communication protocol

√ Suitable for flow measurement of various conductive liquids (conductivity>5μs/cm)
