Rainfall Monitoring

1.Rainfall Monitoring product overview

Rainfall Monitoring obtains accurate and timely rainfall measurements, providing real-time rainfall and accumulated rainfall data.SW2 is a fully automatic hydrological online monitoring system based on microwave technology, which can measure water level and rainfall in the channel at the same time.It uses advanced K-band plane radar technology to measure the water level and rainfall of water bodies through non-contact methods, and calculate and output real-time data according to the built-in software algorithm; it can be used for non-contact flow measurement in rivers, irrigation canals, underground drainage pipelines, flood prevention warnings and other occasions; the product has the characteristics of low power consumption, small size, high reliability and convenient maintenance; the measurement process is not affected by factors such as temperature, silt, river pollutants, and floating objects on the water surface.

2.Rainfall Monitoring Application Field

1.Measure water levels and rainfall in rivers, lakes, tides, reservoir gates, groundwater pipelines, irrigation channels, etc.

2.Auxiliary water treatment operations, such as urban water supply, sewage discharge monitoring, etc.

3.Flow calculation, inlet and drainage flow monitoring, etc.

3.Rainfall Monitoring product features

1.Non-contact measurement, calculate flow in combination with cross-sectional parameters, and is not affected by wind, temperature, haze, silt, sand, floating objects, etc.

2.It is suitable for a variety of measurement conditions, and is not affected by corrosion and foam, and can output measurement data of water level and rainfall.

3.The water level uses a flat array radar antenna, with its own angle measurement function, the equipment is small in size and easy to install

4.Convenient configuration software can easily configure parameters according to actual needs to adapt to different usage conditions.

5.Not affected by changes in water vapor, temperature and pressure in the atmosphere

7.Precautions for installation of Rainfall Monitoring

1.Installation environment

There are no huge stones in the test channel blocking the water, no huge vortexes, turbulences, etc.

The test channel section should be straight, stable, and concentrated

The test channel section needs to be hardened, and the measurement section should be regular

The test channel section should be kept smooth to prevent floating objects from accumulating

2.Installation height

Recommended installation height 3-4 meters
