FMCW Frequency Modulated Continuous Wave Radar Level Meter: Measurement Of Large Solid Silos

The high-frequency radar level meter is a level measurement instrument suitable for large solid silos within 120 meters. Compared with other technologies, such as capacitive or guided wave radar, when the material level drops during discharging, it will be subject to a strong tension load, and the FMCW radar has a higher operating frequency, which can effectively avoid this problem and reduce the number of instruments. damage and collapse of the warehouse roof.

In addition, the antenna used by the high-frequency radar level meter is smaller, which can better adapt to high dust conditions, and has a narrow beam width, which can effectively avoid obstacles.

FMCW radar usually operates in the W band (76~81GHz). Its electromagnetic wave has a shorter wavelength, can better reflect inclined solid surfaces, and has better measurement accuracy and reliability. At the same time, the FMCW frequency modulated continuous wave radar level meter transmits and receives signals at the same time, which can effectively reduce the occurrence of wave loss in solid measurements and provide more accurate and reliable measurement results.

Therefore, FMCW radar has become a widely used measurement tool in high-dust solid silos, and has good application results in PP powder, PE powder and other media in the chemical industry.
