Wholesale supply of water level monitoring stations

　　Automatic rainfall and water level monitoring station The system is capable of real-time and accurate monitoring of water level changes and integrates a series of high-tech equipment, including high-precision sensors, sensitive rain gauges, and image monitoring systems. Once the water level exceeds the preset safety threshold, the system will immediately trigger an over limit alarm mechanism and notify relevant personnel in a timely manner through various means. At the same time, the system also has powerful data storage and analysis functions, which can deeply mine and intelligently analyze historical water level data, providing scientific basis for the safety management of reservoirs.

1Automatic rainfall and water level monitoring station Product Overview

SW2 is a fully automatic hydrological online monitoring system based on microwave technology, which can simultaneously measure water level and rainfall in channels.
