80G Radar Water Level Gauge

Product Manual

The AN-WLG-WC04/80G radar water level gauge is a self-developed non-contact water/liquid level detection device. It is widely used for water level monitoring of rivers, lakes and reservoirs, as well as auxiliary water treatment operations. Adopting FMCW modulation technology, it enables all-weather real-time water level measurement, free from interferences of weather, temperature, water vapor and aquatic pollutants. Built-in high-efficiency data processing algorithms guarantee high measurement precision. Three standard electrical interfaces are available: RS232, RS485 (default) and 4～20mA.

This device adopts high-frequency microwave radar technology. The sensor emits electromagnetic waves to the water surface and receives reflected echoes, so as to calculate the distance and orientation between the sensor and water surface. It achieves millimeter-level high precision, high reliability and easy installation. Equipped with a dedicated water surface fluctuation filtering algorithm, it delivers stable and accurate monitoring data. Compared with traditional radar level meters, it features higher accuracy, lower power consumption and smaller size.
