KLD802 Radar Level Sensor With Non Contact PTFE Lens Antenna For Continuous Level Measurement
Introduction
The KLD802 Radar Level Sensor is a highly advanced device. It features a non-contact PTFE lens antenna, which is a key component for its outstanding performance. This antenna design allows for continuous level measurement without the need for physical contact with the measured substance. It is especially suitable for a wide range of applications where accuracy and reliability are essential. The sensor utilizes radar technology to emit electromagnetic waves and then analyzes the reflected signals to precisely determine the level of liquids or solids. With its durable construction and precise measurement capabilities, it can effectively operate in various industrial environments, providing accurate and real-time level data for efficient process control and inventory management.
Feature
1. Non-contact measurement.
The measurement will not be affected by changes in medium properties or process conditions, such as temperature, pressure or dust intensity. Adjusting settings is easy, eliminating the need for filling and emptying containers, saving time during instrument start-up, and making the instrument virtually maintenance-free.
2. Large measuring range and small blind area
The measurement range is 0.1~120m, which basically meets the measurement requirements of on-site working conditions.
3. The antenna size is small, the beam angle is small, and the focusing ability is strong
It is convenient for radar on-site installation. It has stronger anti-interference ability for the environment inside the tank. For example, there are stirring, heating coils, baffles, etc. in the tank or the measurement effect in the straight pipe is still good.
4. High precision
The accuracy can reach ±2mm, which can fully meet the accuracy requirements of non-metering field working conditions.
5. The signal wavelength is short
It is better for the measurement of the level of powder, particles and so on.

Installation Method
Flange installation
When using flange installation, the minimum distance between the instrument and the tank
wall should be 200mm.
① datum plane
② vessel center or axis of symmetry
Hoisting Installation
Radar level sensors can measure liquids, slurries and solids. The radar level sensors has pressure and temperature resistance, and will not be affected by the measurement medium during measurement, and has high measurement accuracy. In terms of installation, if it can be used and installed correctly, it will have a good measurement effect and ensure accurate data.
For the installation of radar level sensor, we should pay attention to two points:
One is to ensure the vertical incident material level after aiming at the target material level, and the other is to avoid false echoes.So when installing, we suggest:
1. The radar level gauge should be installed at least 20CM away from the container wall, preferably about 1/6 of the container diameter. Do not install the radar level gauge above the water inlet pipe and in the center of the container, otherwise there will be many false echoes, which will interfere with normal signal reception.
2. If the radar level gauge cannot maintain an appropriate distance from the container wall due to the relatively small diameter of the container or other reasons, false echoes will appear on the container wall and the radar level gauge when the distance is small, so the debugging It is necessary to store false echoes in order to avoid errors in the future.
3. If the installation container is concave or conical, you need to pay attention to the installation. When using it, the radar beam of the radar level gauge reaches the lowest point of the bottom of the tank. If the liquid level is lower than this point, it cannot be measured. The purpose of adjusting the lowest point is to ensure the accuracy of the measurement data.
