River level measurement

1.River level measurement product overview

River level measurement is mainly used to collect water level data of reservoirs, lakes and rivers, and monitor rainfall through changes in river level to reduce flood disasters.River level measurement is a fully automatic hydrological online monitoring system based on microwave technology, which can simultaneously measure the water level in the channel. It uses advanced K-band planar radar technology to measure the flow velocity and water level 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. River level measurement application areas

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

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

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

3. River level measurement product features

1. Non-contact measurement, combining cross-sectional parameters to calculate flow, not affected by wind, temperature, haze, silt, floating objects, etc.

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

3. The flow velocity and water level adopt a planar array radar antenna with built-in angle measurement function. The equipment is small in size and easy to install.

4. Convenient configuration software can configure parameters conveniently 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. Notes on River Level Measurement Installation

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.

2. Installation height

Recommended installation height 3-4 meters

3. Installation direction of flow meter

The velocity meter beam is recommended to face the incoming water direction
