Intelligent Radar Level Meter Description - Focus on Microfluidic Control Technology

Measuring principle
Very short microwave pulses with very low emission energy are transmitted and received through the antenna system. Radar waves run at the speed of light. The operating time can be converted into level signals via electronic components. A special time extension method ensures stable and accurate measurements in a very short time. Even if the working conditions are more complicated, there are false echoes, and the echo of the material level can be accurately analyzed by using the microprocessing technology and debugging software.

The antenna receives the reflected microwave pulse and transmits it to the electronics. The microprocessor processes this signal to identify the echo generated by the micropulse on the surface of the material. The correct echo signal recognition is done by intelligent software and the accuracy can reach millimeter level. The distance D from the surface of the material is proportional to the time travel T of the pulse:
D=C×T/2
Where C is the speed of light
Since the distance E of the empty can is known, the level L is:
L=E-D
Output
By setting the empty tank height E (= zero), full tank height F (= full scale) and some application parameters, the application parameters will automatically adapt the instrument to the measurement environment. Corresponds to 4-20mA output.
Application media:
The RD-800 series radar level gauge is suitable for non-contact continuous measurement of the liquid, slurry and granular material level. It is suitable for large temperature and pressure changes; there are occasions where inert gas and volatile exist. The microwave pulse measurement method is used and can work normally in the industrial frequency band. The beam energy is low and can be installed in various metal or non-metal containers or pipes without harm to the human body and the environment.
