Hydrology online monitoring system

1. Product Overview of Hydrological Online Monitoring System

The hydrological online monitoring system is also called the small and medium-sized river hydrological monitoring system. The hydrological online monitoring system is suitable for remote monitoring of real-time water and rain conditions in rivers, reservoirs, etc., and is used to diversify the operation of water conservancy facilities such as rivers, lakes, and reservoirs. It uses advanced K-band planar radar technology to measure water levels and rainfall in a non-contact manner. Based on the built-in software algorithm, it calculates and outputs real-time cross-sectional flow and cumulative flow; it can be used in rivers, irrigation canals, underground drainage pipe networks, Non-contact flow measurement for flood prevention and early warning and other occasions; this product has the characteristics of low power consumption, compact 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 of hydrological online monitoring system

1. Water level and rainfall measurement in rivers, lakes, tides, reservoir gates, underground water pipe networks, irrigation canals, etc.

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

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

3. Product features of hydrological online monitoring system

1. Non-contact measurement, combined with cross-section parameters to calculate flow, is not affected by wind, temperature, haze, sediment, floating objects, etc.

2. Suitable for a variety of measurement conditions, not affected by corrosion and foam, and can output measurement data of flow rate, water level, and flow rate.

3. The flow velocity and water level adopt a planar array radar antenna, which has its own angle measurement function. The equipment is compact and easy to install.

4. Convenient configuration software can conveniently 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 hydrological online monitoring system

1. Installation environment

There are no huge rocks blocking water in the test canal section, and there are no huge whirlpools, turbulence, etc.

The test canal 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 accumulation of floating objects
