Wireless measurement · Zero pressure loss accuracy · A new era of conductive fluid monitoring
The YFM4800E NB wireless electromagnetic flowmeter applies Faraday's electromagnetic induction principle combined with industrial-grade wireless IoT (LoRaWAN / NB-IoT / 4G) to measure conductive liquid flow. Its full-bore design has no moving parts or flow-restricting elements, eliminating pressure loss. Battery power and wireless transmission enable installation in locations where cabling or power access is impractical, including buried pipelines and hazardous/explosion-risk areas.

Product Advantages

• True zero pressure loss: full-bore measurement, 100% unobstructed flow, eliminates energy loss and can reduce pumping costs by 15%+
• Wireless deployment: avoids extensive cabling, lowers installation costs and enables safer setups in explosive or hard-to-wire zones
• Robust interference resistance: adaptive electrode technology and digital signal filtering to mitigate bubble and solid-particle interference; accuracy up to ±0.5% RD
• Extended service life: battery operation with typical 8–10 years life (with 4 reports/day); IP68 submersible protection; maintenance-free lining and electrodes designed for life-of-instrument use
• System integration: direct data integration with SCADA and smart water management platforms, API compatibility, and support for automated energy-efficiency reporting (ISO 50001)

Core Application Areas

• Water management and environmental protection: municipal supply networks, wastewater discharge metering, real-time irrigation monitoring
• Chemical and pharmaceutical industries: process flow control for strong acids/alkalis, slurries and corrosive media (optional PTFE/PFA lining)
• Food & beverage: sanitary batch measurement of juices, dairy and syrups (3A/EHEDG compliant options)
• Mining and metallurgy: measurement of high-wear media such as slurries, tailings and cooling circulation water
• Energy systems: cooling water measurement for power plants, boiler feedwater and heat/cold media for distributed energy stations

Pain points addressed
Solves constraints on cable routing in buried pipelines, cable degradation in highly corrosive environments, and high costs/complexity of wiring in explosive-risk zones.
