Read： 476 Time：20months ago Source：Transform the World with Simplicity

Guided wave radar level gauge is a high-precision instrument mainly used in industrial manufacturing and chemical industry, which can realize non-contact, high reliability, anti-corrosion, and non-media-restricted level measurement. It transmits high-frequency pulse signal and receives the reflected signal to determine the height of the liquid level, which has the advantages of wide measurement range, high precision and small measurement error. The principle of the

guided wave radar level gauge is as follows: the signal transmitter introduces a high-frequency pulse signal into the antenna through a cable or a dielectric waveguide, and forms an electric field and a magnetic field. The energy of the magnetic field in the antenna is converted into a weak electromagnetic wave, which propagates and reflects along the surface of the medium or liquid. The reflected electromagnetic wave is collected by the antenna and converted into an electrical signal, and the signal is processed to obtain the liquid level height.

guided wave radar level gauge has a very wide range of applications, not only can be used for the level measurement of various containers, but also can be applied to the measurement of solid materials and level measurement. In the chemical industry, food processing, medicine and other fields have a wide range of applications, such as for acid and alkali, corrosive liquid level detection, as well as for high temperature, high pressure, easy to move and fluctuate the liquid for stable measurement.

Compared with the traditional level gauge, the guided wave radar level gauge has the advantages of more sensitive, accurate, simple and durable, which can meet the needs of various level measurement in the industrial production process. It uses the transmission medium is not affected by the environment, will not be limited by temperature, pressure and other factors, and does not need to directly contact the surface of the material, to avoid the media corrosion or pollution and produce greater damage.

guided wave radar level gauge plays an important role in the current industrial production with its high precision, reliability, simplified working principle and wide range of application. In the future, it will continue to provide help for liquid level control and production management in more industries.
