Radar Level Transmitter RS485 Communication IP68 Water Resistance For 0.1-15/20m Measurement Range

• Introduction

1.1 Product Overview

KWL801B-RS485 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.

6.Installation instructions

6.1 Inspection before installation

(1) Take the sensor out of the packaging box, carefully check the packing list according to the instruction manual, and check whether the equipment accessories are complete .

(2) Carefully read the product instruction manual and product certificate .

(3) Check whether there is any damage to the appearance of the instrument, especially whether the main unit is intact, and be careful to place the main unit properly to prevent it from being knocked over.

6.2 Radar level sensor installation

6.2.1 Check before installation

Please check before installing the sensor as follows:

Whether there are trees or other debris above the medium at the installation site.

Whether the mounting bracket is installed horizontally.

When the mounting bracket cannot be installed horizontally, you need to adjust the bracket according to gradienter on the surface of the sensor to make sure the sensor is in a horizontal position.

6.2.2 Installation

(1) Ensure that the sensor is perpendicular to the medium surface.

(2) Avoid the transmitting beam from irradiating interference objects and generating false echoes.

See the following for typical working conditions:

Ensure that the radar level meter is installed perpendicular to the medium surface.

Inclination will weaken the received signal amplitude and affect normal ranging.

Attention:

Try to keep the sensor fixed to avoid jitter when installing, and keep the surrounding environment as open as possible.

1. The distance between the sensor and the medium surface is higher than 30cm to ensure that the front face of the sensor (antenna) is perpendicular to the measuring medium.

2. The distance between the sensor and the edge of the tank, the edge of the pool, the edge of the river dam and the edge of the pool is greater than 0.5 meters;

3. Select the position of the water surface with small fluctuations to install the module (try not to install in the water injection port, outlet and other water surface with large fluctuations, the greater the water surface fluctuation, the worse the measurement accuracy)
