Guided wave radar level gauge

Description

Overview and application: Guided wave radar can emit high-frequency microwaves, propagate along the probe rod, and cause reflection due to sudden changes in dielectric constant when encountering the measured medium. 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. Applied to industries such as coal plants, power plants, petrochemicals, and food. characteristic: Can measure any medium with a dielectric constant greater than or equal to 1.4 Suitable for measuring viscous liquids or situations with large temperature and pressure changes ● Suitable for measuring significant volatile gas media ● Used for foam, wall hanging and scaling, surface fluctuation, bubbling or boiling, high-frequency loading and unloading, and ultra-low liquid level conditions Applications of media with changes in dielectric constant or specific gravity ● Used for solid particles and powder media Media with high dust emissions
