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.
