Characteristics And Measuring Principle Of High Frequency Radar Level Gauge

The high-frequency radar level gauge is a radar-type level measuring instrument with a measuring distance of up to 20 meters. The antenna is further optimized, and the new fast microprocessor can perform signal analysis and processing at a higher rate, so that the instrument can be used in various strong corrosive liquids. The radar antenna emits a narrow microwave pulse, which is transmitted through the antenna. The microwave will be reflected after touching the surface of the measured medium. The radar antenna receives the microwave signal and transmits it to the electronic circuit part. The electronic circuit part automatically analyzes the signal. Converted into a level signal, due to the extremely fast propagation speed of electromagnetic waves, this process is almost instantaneous.
