The radar wave water level gauge is a measuring instrument that uses microwave pulses to transmit and receive reflected waves through an antenna. By measuring the time difference between the emitted wave and the reflected wave, combined with the known wave speed, the water level height is calculated. Because radar waves are not affected by external factors such as light, smoke, dust, etc., they have the characteristics of high measurement accuracy and strong reliability. The water level monitoring radar water level gauge adopts a non-contact measurement method, which avoids errors caused by traditional water level gauges due to contact surface friction. At the same time, it uses high-precision time measurement technology to achieve millimeter-level measurement accuracy. radar waves have strong penetration and diffraction capabilities, and can penetrate floating objects, aquatic plants and other obstacles on the water surface to achieve accurate measurement of accumulated water. In addition, radar waves are not easily affected by electromagnetic interference, ensuring measurement stability. water level monitoring radar water level gauge has a long service life and low failure rate. At the same time, it has strong anti-corrosion and lightning protection capabilities, and can operate stably under harsh environmental conditions. The radar water level meter has a simple structure, small size, and is easy and quick to install. In daily maintenance, the radar head only needs to be cleaned regularly, which is easy to operate.

data, the operating status and existing problems of the drainage system can be understood, thereby guiding the construction and improvement of drainage facilities. Long-term monitoring of urban road water accumulation can evaluate the city's ability to prevent floods, and take corresponding measures to strengthen urban flood prevention and improve the city's disaster resistance.
