Operating Manual of Split Radar Level Sensor
1. Introduction
1.1 Product Overview
KWL801C radar level sensor conforms to the standard specifications
outlined in national standard DB50/T 826-2017 for level meters. Its
core component is designed with a fully sealed IP68 waterproofing.
The maximum measurement range of the product extends up to 40
meters, with a minimal blind spot of less than 6 cms.
Due to its higher frequency and broader bandwidth, it achieves
superior accuracy. Additionally, the product includes a fixed
bracket for installation.
1.2 Detection principle
Radar level sensor is based on the principle of time domain
reflection (TDR). The electromagnetic pulse propagates along the
cable or probe with the speed of light. When it meets the surface
of the measured medium, part of the pulse of the radar level meter
is reflected to form an echo return to the pulse transmitter along
the same path, and the distance between the transmitter and the
surface of the measured medium is In direct proportion as the
propagation time of the pulse, hence the height of the level is
calculated.
2. Feature

- 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
