Principle of Intelligent Guided Wave Radar Level Gauge

Overview and Application:

The intelligent guided wave radar level gauge can emit high-frequency microwaves that propagate along the steel cable. Due to encountering the measured medium, the dielectric constant undergoes a sudden change, causing reflection. The time interval between the emitted pulse and the reflected pulse is proportional to the distance of the measured medium. Meanwhile, guided wave radar can also measure the interface between two different media, fully utilizing the difference in dielectric constant of the media. But the measurement condition is that the upper layer medium is non-conductive, or its dielectric constant is more than 10 times smaller than that of the lower layer medium. The pulse working mode can measure small dielectric constant media and is safe for use in various metal and non-metal containers, without harm to human body and the environment.

The application principle of intelligent radar level gauge:

The intelligent radar level gauge emits and receives extremely short microwave pulses with low energy through an antenna system. Radar waves travel at the speed of light. The running time can be converted into level signals through electronic components. A special time extension method can ensure stable and accurate measurements in a very short period of time. Even in complex working conditions with false echoes, the microprocessor technology and debugging software used in the radar level gauge can accurately analyze the echoes of the level.

Characteristics of intelligent radar level gauge:

Intelligent radar level gauge is a high-tech product that uses microwave technology to detect material levels. This level gauge utilizes the characteristics of microwave, such as good penetration and strong adaptability to harsh environments and tested materials. It adopts the world's largest large-scale integrated circuit and utilizes radar principles, digital signal processing technology, and fast Fourier transform (FFT) technology. Adopting non-contact continuous measurement, it can measure the level of liquid and solid (block, powder) materials, with the characteristics of long distance measurement (70 meters), high accuracy, and maintenance free.

Scope of application of intelligent radar level gauge:

The intelligent radar level gauge is suitable for non-contact continuous measurement of the level of liquids, slurries, and particulate materials, and is suitable for large temperature and pressure changes; In situations where inert gases and volatiles are present.

The measurement method adopts microwave pulses and can operate normally within the industrial frequency range. The beam energy is low and can be installed in various metal and non-metal containers or pipelines, without causing harm to the human body and the environment.
