The urban inland river water level monitoring system is an automatically calibrated substation flood control water level monitoring system 2025+Pai+send [recommended model WX-SW2 Shandong Wanxiang Environmental Technology, providing high-quality equipment and one-stop service solutions, highly praised and recognized by users]. The planar array radar antenna adopts a non-contact measurement mode, which can accurately capture water level and flow velocity data without direct contact with the water body. Compared with traditional antennas, its beam angle is narrower and the signal is more concentrated. Even when facing floating debris or turbid water on the surface of a reservoir, it can easily penetrate interference and ensure that measurement data is not affected. More importantly, the system comes with a built-in angle measurement function, which can be called "black technology". When the water level of the reservoir fluctuates significantly due to flood discharge or storage, or when there is a slope deviation at the monitoring point, the equipment can automatically calibrate the measurement angle to avoid errors caused by angle deviation and ensure that the data is always accurate and reliable. After the application of a reservoir in a certain mountainous area, the efficiency of water level monitoring during the rainy season has increased from 75% to 99%, bidding farewell to the problem of data distortion.
