Radar Water Level Gauge
- Product No.:RL3000
A non-contact planar 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 gradient, water vapor on the water surface, pollutants, and sediment in the water. Compared with the traditional pulse horn water level gauge, it has the characteristics of small size and stable signal. The optimized algorithm can make the measurement result more accurate.
Features
1. The weight is less than 900g, and the structure is compact and light;
2. Non-contact, safe and low loss, less maintenance, not affected by sediment, etc.;
3. Monitoring can also be carried out under high flow rate 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 function of integrated RTU can be selected to simplify the difficulty of system design;
7. A variety of interface methods, both digital interface and analog interface, easy to access the system;
8. Multiple trigger modes: cycle, trigger, manual, automatic;
9. The installation is very simple, and the amount of civil works is very small;
10. Smooth antenna design, the appearance of insects or spider webs is no longer a problem;
