Product Description:
The KWL801B-RS485 radar level sensor is a state-of-the-art device
conforming to the national standard DB50/T 826-2017 for level
meters. Its core component employs a fully sealed IP68 waterproof
design, ensuring that the product stays safe even in harsh
environments.
The maximum range of measurement of the KWL801B-RS485 radar level
sensor extends up to 40 meters, with an ultra-minimal blind spot of
less than 6 cms. The product offers superior accuracy, thanks to
its higher frequency and broader bandwidth.
This radar level sensor features a fixed bracket for quick and easy
installation. We understand that the installation process is
equally essential, and hence we designed a simple installation
method that is both time-saving and accurate.
Features:
- Based on the self-developed CMOS millimeter-wave RF chip
- More compact RF architecture
- Higher signal-to-noise ratio
- Smaller dead zone
- 5GHz working bandwidth
- Higher measurement resolution and measurement accuracy
- Less influence by the interference in the installation environment
- More convenient of installation and
- Modern design of integrated flat antenna

Radar Level Sensor Explained
Radar level sensor is a device that uses the principle of time
domain reflection (TDR) to accurately measure the level of liquids
or solids. The sensor uses an electromagnetic pulse that propagates
along a cable or probe at the speed of light.
When the pulse meets the surface of the measured medium, part of it
is reflected back to the pulse transmitter as an echo. The pulse
then travels back along the same path it came from. The distance
between the transmitter and the surface of the measured medium is
in direct proportion as the propagation time of the pulse.
Using the propagation time of the pulse, the radar level meter can
calculate the height of the medium being measured. This is achieved
by using the time taken for the pulse to travel from the
transmitter to the surface of the measured medium and back again to
the transmitter.
