Due to its unique geographical climate, China is a country with severe water and drought disasters, accounting for about 70% of all natural disaster losses. Especially in the plum rain season in June in the south, the water level will suddenly rise during every rainstorm, so it is too late for flood warning.

Ultrasonic sensors are used to monitor water levels and can effectively monitor high-density heavy rainfall and extreme weather conditions in a short period of time, contributing to flood warning.

Ultrasonic sensors have the following advantages in monitoring water levels

1. Real time monitoring of river water level, expandable monitoring of rainfall, water quality, and flow velocity.

2. When the water level exceeds the limit, the sensor malfunctions, or the monitoring terminal battery voltage is low, an alarm will be immediately triggered.

3. It can be linked with the drainage pump station to automatically control the start and stop of the drainage pump group based on the river water level.

4. Support integration with other comprehensive monitoring application platforms through OPC, database, and other forms.
