Integrated Radar Water Level Gauge

Product Description

A non-contact plane-integrated radar water level gauge for surface water level measurement, which uses frequency-modulated continuous wave radar (FMCW) technology to measure the liquid level. It is an energy-saving, non-contact measurement technology. It is not affected by temperature gradients, water vapor, pollutants and sediments in the water, and the optimized algorithm can make the measurement results more accurate. Compared with the traditional pulse horn type water level gauge, it has the characteristics of small size, convenient installation, and low maintenance.


1. The weight is less than 900g, the structure is compact and light, and the wind and anti-shake ability is strong;

2. Non-contact, safe and low loss, less maintenance, not affected by sediment, etc.;

3. Monitoring can also be performed under high flow velocity conditions during flood periods;

4. The power supply circuit adopts anti-reverse connection and lightning protection design;

5. The power consumption of the system is low, and the general solar power supply can meet the measurement needs;

6. The built-in angle and attitude sensor can sense the installation inclination, which is convenient for installation and debugging;

7. The installation is very simple, and the amount of civil works is very small;

8. The flat-panel antenna design avoids the hidden dangers of insects' nesting and netting and the influence of fog on radar signals;

9. Fully waterproof design, suitable for field use; 

10. Integrated RTU function, data is directly uploaded to the server, simplifying the difficulty of system integration;

11. Built-in low-power Bluetooth, can be directly debugged and set parameters through the mobile phone APP on-site, without computer connection.
