CAT1 Wireless Level Transmitter

4G Direct Connect · Cloud Monitoring & Control — Smart IoT Solution for Industrial Liquid Level Monitoring

YUNYI CAT1 Wireless Liquid Level Gauge is an intelligent IoT monitoring device based on 4G CAT1 communication technology. It integrates high-precision liquid level sensing, data acquisition, and wireless transmission, directly uploading liquid level data to the cloud platform via carrier 4G networks. This delivers a liquid level monitoring solution requiring no wiring, no gateways, and full-coverage communication. Featuring an ultra-low power design and an integrated high-performance lithium battery, the device delivers an extended battery life of 3-5 years. It is particularly suited for dispersed liquid level measurement scenarios lacking mains power supply and requiring remote monitoring.
