1. Hydrological flow station Product Overview

The automatic rainfall and water level monitoring station integrates advanced sensor technology and data analysis system, which can monitor rainfall and water level changes in real time, quickly capture small changes in rainfall, and transmit data in real time to the monitoring center for display.

WX-SW1 is a fully automatic hydrological online monitoring system based on microwave technology (with provincial CMA certificate), which can simultaneously measure the water level and rainfall in the channel. It uses advanced K-band planar radar technology to measure the water level and rainfall of the water body in a non-contact manner, and calculates and outputs the real-time cross-sectional flow and cumulative flow according to the built-in software algorithm; it can be used for non-contact flow measurement in rivers, irrigation canals, underground drainage networks, flood prevention and early warning, etc.; the product has the characteristics of low power consumption, small size, high reliability, and easy maintenance; the measurement process is not affected by factors such as temperature, sediment, river pollutants, and floating objects on the water surface.

2. Application fields

7. Installation precautions

1. Installation environment

There are no huge rocks blocking the water in the test channel section, and there are no huge whirlpools, turbulent flow, etc.

The test channel section should be straight, stable and have concentrated water flow

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.
