KWL800 65m Range 76-81GHz FM Continuous Wave Radar Water Level Sensor with RS485 Modbus Communication
Introduction
KWL800 radar level sensor series products refer to frequency modulated continuous wave (FMCW) radar products working at 76-81GHz. The maximum range of the product can reach 65m, and the blind zone is within 10 cm. Because of its higher operating frequency, larger bandwidth, and higher measurement accuracy.
Feature
⚫ Based on CMOS millimeter-wave radio frequency chip, realize more compact radio frequency
architecture, higher signal-to-noise ratio, and smaller blind area.
⚫ Higher measurement resolution and measurement accuracy.
⚫ Narrow antenna beam angle is 6°, the interference in the installation environment will have less
impact on the instrument, and the installation is more convenient.
⚫ Integrated lens design, compact size.

Installation Method
There are two points to pay attention to during installation:
(1) Ensure that the meter is perpendicular to the water surface.
(2) Avoid emitting beams from irradiating interference objects and generating false echoes.
See the following points for typical working conditions.
Ensure that the water level sensor is installed vertically to the water surface, and the tilt will weaken the received signal amplitude, which will affect the normal distance measurement.
Make sure that there are no interference objects within the beam range, such as the banks of rivers.
The instrument should be installed at least 20cm away from the side wall, and the underground pipe network should be installed as close to the center of the well as possible, otherwise the well wall will easily generate interference signals, which will affect the measurement and judgment.
