Water level monitoring is a crucial link in water resource management, flood prevention, and disaster mitigation. By keeping track of water level changes in real-time, it can provide scientific basis for the operation and regulation of water conservancy projects, urban flood prevention planning, and agricultural production irrigation. Precise water level data serves as the foundation for early warning of flood disasters, ensuring the safe operation of reservoirs, and optimizing the allocation of water resources.
With the development of science and technology, water level monitoring equipment based on radar technology has gradually become a commonly used measuring device in the industry. The radar water level gauge, also known as the water level radar, is an electronic device that uses electromagnetic waves to detect targets. It is mainly used in tasks such as water conservancy monitoring, sewage treatment, and flood prevention early warning. Its measurement principle is based on the propagation characteristics of electromagnetic waves. The radar sensing antenna of the device emits radar pulses, and then the antenna receives the pulses reflected back from the water surface and accurately records the time t of this process. Since the propagation speed c of electromagnetic waves is a fixed constant, the distance d from the device to the water surface can be calculated according to the formula. By continuously emitting electromagnetic waves and receiving the echo waves, the device can obtain information such as the distance from the water level to the electromagnetic wave emission point and the rate of change of the distance (radial velocity), thus achieving precise monitoring of the water level.
The Water Level Monitoring System consists of three parts: the microwave transmitting antenna sends electromagnetic waves to the water surface, the signal processing module calculates the echo time, and the data transmission unit enables remote and automated communication. This not only improves the measurement efficiency but also realizes remote monitoring and intelligent early warning through the integration of the Internet of Things, providing reliable technical support for modern hydrological monitoring.
It belongs to a non-contact measurement method, avoiding direct contact with the water body. It will not be affected by factors such as water body corrosion and biological attachment, which may influence the measurement accuracy and the service life of the equipment. Moreover, it has a high measurement accuracy and can quickly and accurately reflect water level changes, providing timely and reliable data support for relevant decision-making.
