YLTW327 Wireless level transmitter

Instant deployment, instant measurement · Fearless in deep waters · Open-water monitoring expert

The wireless submersible level sensor utilizes the diffusion silicon piezoresistive principle and integrates an industrial-grade wireless IoT module (LoRaWAN/NB-IoT/4G). It measures hydrostatic pressure by directly immersing the sensor into the bottom of the medium to monitor liquid levels. Featuring a fully sealed titanium alloy probe with IP68 protection and self-cleaning breathable membrane technology, it is specifically designed for open environments such as sewage wells, rivers, and firewater tanks. No brackets or power wiring required; deployment can be completed in just 5 minutes, providing an extremely simple solution for distributed liquid level monitoring.

Product Advantages
1. 5-minute ultra-simple deployment: Simply place it in the water body without the need for brackets or cables, reducing installation costs by 95%.
2. Silt-adaptive; inverted cone-shaped probe prevents silt accumulation, breathable membrane automatically cleans itself, and lifespan in muddy environments is increased by 3 times.
3. Ultra-long battery life: Battery lifespan of over 10 years (with twice-daily data reporting), standby power consumption <1μA, and full climate adaptability from -40°C to 85°C.
4. Multi-level lightning protection design: 8kV surge protection + equipotential grounding, zero failure rate in high-risk lightning areas.
5. Cloud-based intelligent early warning: AI-driven detection of sudden water level changes (heavy rain/leaks), multi-level alerts via WeChat/SMS, and integrated pump/valve control.

Core Application Areas
✅ Urban Flooding Early Warning: Real-time liquid level monitoring of rainwater wells and drainage networks, linked to the smart water management platform.
✅ Environmental Protection Monitoring: Water level and overflow alarms for rivers, lakes, and sewage treatment plant collection wells.
✅ Agricultural Irrigation: Remote water level management of farmland reservoirs and irrigation channels, viewable with a single click on a mobile phone.
✅ Fire Safety Systems: Legal water level monitoring for rooftop water tanks and fire protection water tanks (compliant with NFPA 22 standards).
✅ Industrial Water Collection: Unmanned monitoring of mine seepage pits and industrial rainwater collection ponds.

Addressing Four Key Challenges:
✦ Difficulty in obtaining power in remote areas ✦ Silt blockage of traditional sensors ✦ Lightning damage to cables ✦ High maintenance costs for dispersed monitoring points
