Radar Water Level Gauge SCJ-LD40
The SCJ-LD40 Radar Water Level Gauge is a non-contact water level measurement device based on advanced microwave radar technology, providing accurate and reliable water level monitoring. Featuring a compact structure, lightweight design, and easy installation, the device is suitable for applications in rivers, open channels, reservoirs, sewage pipeline networks, water tanks, and other water monitoring environments. The SCJ-LD40 adopts a 24 GHz microstrip planar array antenna combined with Frequency Modulated Continuous Wave (FMCW) technology. The device features high measurement accuracy, low power consumption, compact size, lightweight construction, strong resistance to environmental interference, and excellent reliability and maintainability. Designed for all-weather operation, it is particularly suitable for unattended monitoring in remote field environments and mountainous areas. Based on the microwave reflection principle, the device provides strong anti-interference capability and achieves millimeter-level measurement accuracy. It is unaffected by weather conditions, atmospheric pressure, geographical environment, or other external factors, enabling stable operation in complex field conditions. The SCJ-LD40 can quickly adapt to different monitoring environments after relocation, ensuring stable performance, long service life, and maintenance-free operation.
