Products Description
Radar water level sensor is a commonly used water level monitoring device. By using radar beams to measure the distance between the water surface and the radar sensor, accurate monitoring of river water levels is achieved.
Our ARLGS-09 radar water level sensors can be customized with 4-20mA or RS485 signal output. The measuring range is 15m-35m-85m-150m optional. It is widely used in various functional scenarios such as river, lake, water conservancy detection, drainage pipe network, hydrological station, agricultural irrigation, tide and so on.
Radar Water Level Sensor Applications：
1.Wastewater treatment: Wastewater treatment plants require constant monitoring of water levels to ensure proper operation, and radar water level gauges can play a role in this area.
2.Hydrographic measurement: Hydrographic measurement of rivers, lakes and other waters requires high-precision water level meters to monitor water levels, and radar water level meters have become a viable option.
3.Agricultural irrigation: Agricultural irrigation requires constant monitoring of water levels to regulate water flow. Radar water level meters can meet its needs for high accuracy, high range and anti-interference capabilities.
Product Features
●Millimeter-wave radar has a maximum measurement accuracy of ±2mm and a minimum measurement blind zone of 0.1m;

Radar Water Level Sensor Working Principle
Radar water level sensor series products refer to frequency modulated continuous wave radar products working at 76-81GHz. They are non-contact measuring instruments. It calculates the distance and position between objects by emitting radar signals and receiving reflected signals, and measuring the propagation time and wavelength of the signals.
The general principle of frequency modulated continuous wave radar level meter is that the radar emits electromagnetic waves on the top of the tank. The electromagnetic waves are reflected by the medium and are received by the radar. The frequency difference δf between the received signal and the transmitted signal is in a certain proportion to the distance R from the medium surface: R=C (speed)*δf (frequency difference)/2/K (frequency modulation slope).
Since the speed of light C and frequency modulation slope K are known, the frequency difference δf can be estimated, and the distance R to the material surface at the radar installation location can be obtained. Then from the known total height, subtract the spatial distance from the radar to the water surface to the material surface (referred to as empty height), the height of water level-material level is obtained.
