LDE electromagnetic flowmeter is a sensor-type instrument which uses Faraday's law of electromagnetic induction to measure volume flow. It is MCU embedded technology, digital excitation and CAN Fieldbus which is advanced technology in international. LDE electromagnetic flowmeter output 4~20mA current signal for recording, regulating and controlling. It is widely used in chemical industry, environmental protection, metallurgy, medicine, paper making, water supply and drainage and other industrial. It is not only used to measure flow of conductive liquid but also liquid-solid two-phase flow, high-viscosity flow and salt, acid and alkali liquid volume flow.
