The radar water level monitoring station is a fully automated online hydrological monitoring system based on microwave radar technology. It uses K-band planar radar to measure water levels non-contactly, with a ranging range of 0.1 to 40 meters, an accuracy of ±5 mm, and a resolution of 1 mm. It is unaffected by temperature, sediment, pollutants, or floating debris, and is suitable for scenarios such as rivers, reservoirs, irrigation canals, and flood control early warning systems.
The radar water level monitoring station is a fully automated online hydrological monitoring system based on microwave radar technology, primarily used for real-time measurement of water level changes in rivers, lakes, reservoirs, irrigation canals, and underground drainage networks. The system employs K-band planar radar technology, transmitting electromagnetic waves to the water surface in a non-contact manner and receiving the reflected signals. The distance between the sensor and the water surface is calculated based on the time difference between transmission and reception, thus obtaining real-time water level data. The non-contact measurement design ensures that the equipment does not directly contact the water body or pollutants, and the measurement process is unaffected by factors such as temperature, sediment, river pollutants, and floating debris.
In terms of technical parameters, the radar water level monitoring station has a water level ranging range of 0.1 to 40 meters, a ranging accuracy of ±5 mm, and a ranging resolution of 1 mm. The equipment operates in a temperature range of -45℃ to 85℃ (non-freezing condition). Power is supplied by a combination of solar panels and batteries, with selectable solar power of 10W or 30W, and battery parameters of DC 3.7V 10Ah. The support structure consists of a 3-meter vertical pole and a 3-meter horizontal arm. The equipment features low power consumption, compact size, high reliability, and easy maintenance. Signal output uses the RS485/MODBUS protocol, and the data acquisition interval can be set from 1 to 5000 minutes.
In practical applications, radar water level monitoring stations are widely deployed in rivers, lakes, tide zones, reservoir gates, underground water pipe networks, irrigation canals, and other scenarios. The equipment can assist in water treatment operations, such as urban water supply and sewage monitoring, and can also be used for flow calculation and inflow/outflow monitoring. The system integrates data acquisition, processing, in-depth analysis, and early warning issuance functions, enabling real-time monitoring of water level changes and providing real-time data updates. When the water level reaches or approaches the warning level, the system can automatically issue an early warning signal, providing data support for hydrological forecasting, water resource management, and flood and drought control. The monitoring platform supports direct access via mobile phones and PC browsers, and features real-time data display, historical data query, data curve analysis, SMS alarms, and threshold settings. The device can also be optionally equipped with a rainfall monitoring function, measuring rainfall intensity from 0 to 4 mm/min with an accuracy of ±0.2 mm.
