Wireless magnetic flap level gauge

Yunyi Waterproof Wireless Magnetic Level Sensor for Marine Ballast Tanks DNV GL Certified

Wireless Magnetic Flip-Type Level Gauge integrates an industrial wireless IoT module (LoRaWAN/NB-IoT) into the classic magnetic flip-type level gauge.

This Wireless Magnetic Flip-Type Level Gauge combines robust stainless-steel construction with industrial IoT technology (LoRaWAN/NB-IoT) to deliver reliable, dual-output liquid level monitoring. It features a magnetic coupling mechanism that drives highly visible bi-color flippers for local reading, while transmitting real-time data to the cloud for remote access. Ideal for hazardous chemical and fuel storage tanks, it eliminates the need for risky manual checks and ensures 24/7 visibility. With its fail-safe design and corrosion-resistant materials, this gauge offers a smart, secure solution for industrial tank monitoring, reducing operational risks and maintenance costs.

Specification:

Model	YLMW500
Medium density	≥ 0.5g/cm3
Medium pressure	0-15Mpa (accept customize)
Medium temperature	-40℃ ～ 450℃
Medium viscosity	≤ 0.4Pa.S (Choose jacket type for medium with high viscosity or low temperature easy to crystallize)
Output	4-20mA two wires
Tube material	Standard 304 stainless steel(optional for the other)
Protection Level	IP65

Advantage:

Dual-channel reliable monitoring: Mechanical flip-column on-site visualization + 4-20mA/HART wireless remote transmission dual backup, safety level improved by 200%.
Zero Power Upgrade: Battery-powered (lifespan 5-8 years*), directly install on existing magnetic flip-type gauges, upgrade downtime < 1 hour.
Extreme Condition Adaptability: Withstands pressure up to 40 MPa/-0.1 MPa vacuum, temperature range -196°C to 450°C, resistant to strong vibrations/corrosion (optional Hastelloy float).
Intelligent Alarm Management: High/low liquid level WeChat/audio-visual dual alarms, historical data traceability, and prediction of foam/false liquid level phenomena.
Seamless Integration: Compatible with Modbus RTU over LoRa, direct connection to DCS/SCADA, and support for OPC UA data cloud uploading.
