Wireless Electromagnetic Flowmeter

Wireless Measurement · Zero Pressure Loss Accuracy — A New Era in Conductive Fluid Monitoring

YUNYI wireless electromagnetic flowmeter employs Faraday’s electromagnetic induction principle, integrated with industrial-grade wireless IoT technology (LoRaWAN/NB-IoT/4G), specifically designed for monitoring the flow of conductive liquids. With no moving parts or flow obstructions, they completely eliminate pressure loss. Through dual innovations—battery power supply and wireless transmission—they address industry pain points such as difficult wiring in hazardous areas and power extraction challenges in underground pipelines. This provides a fully maintenance-free metering solution for water and corrosive media across all scenarios.
