Radar Level Meter

The radar level meter is a high-tech product listed by our company, which integrates micro-wave, embedded technology and a digital signal process. The non-contact measuring instrument, which was developed by our company independently, is suitable for a harsh environment, and the liquid & material level measurement of many special conditions. All indexes of the radar level meter have reached international advanced level and have achieved the ability to substitute importation.
Principle:
the radar level meter adopts the frequency modulated continue wave (fmcw) principle, and uses the frequency difference between the emitted signal and the received signal to confirm the target distance. In operation, the antenna sends micro-waves which have a continuous frequency linearity change and will be reflected when it reaches medium surface, and is then received by the same antenna. There is frequency difference between the received signal and the emitted signal because of the frequency linearity change. This frequency difference is proportional to the distance, making it possible to calculate distance by frequency.
