▶ Measurement Principle
The product utilizes a composite measurement with a static pressure sensor and a conductivity sensor to detect waterlogging. It senses waterlogging through changes in water pressure caused by the water level. In the absence of waterlogging, it reports safely every 6 hours (configurable). When waterlogging is present, it reports every 5 minutes (configurable).
▶ Key Features
▶ Measurement Parameters: Water Level, Conductivity, Temperature, Signal Strength
▶ NB-IoT Model: 0-0.5 meters (after installation, with signal stronger than -80dB)
▶ LORA RF model: 0-1.6 meters
Stainless steel and POM housing;
▶ Static pressure, electrode composite sensor
Integrated dedicated antenna;
Battery replacement is convenient, reducing O&M costs.
▶ Compact size, ground burial installation, does not affect urban scenery.
▶ Both NB and LORA models support remote OTA updates.
All parameters support remote settings.
▶ Equipped with a Ping An Report feature;
▶ Holds: multiple patents and software copyrights.
Application Scenarios
Measurement and early warning of waterlogging in municipal roads, park roads, and important facilities (such as transformers and other electrical facilities, power stations, substation, etc.).
Installation Location: Road curbs, side-hole installation.
Important Note: When using NB-IOT for direct wireless upload, always confirm the NB signal strength and stability at the installation point, as this may affect the reliability of data transmission. If the quality of the NB signal cannot be confirmed, please opt for the more stable LoRa RF model. The default choice for the NB model at factory is: Telecom Operators!
