RG7 measures the level by using a so-called Frequency Modulated Continuous Wave (FMCW).
The system transmits a continuous wave at a certain frequency of 120 GHz, which is then modulated over a period of time T.
This gives the transmitted signal a “time stamp".
The signal travels then to the target level and part of it is reflected back. The radar will detect the reflected signal and compare it to the original one by mixing them and processing the resulting signal.
By comparing the reflected wave with the original signal at any given moment of time, a frequency shift Δf can be observed.
This shift allows determining the range from the sensor head to the surface of target level.
Since the radar wave are minimally affected by the tank content and its environment like temperature and pressure, radar measurement is proven to be the most reliable gauging method in most applications.
Additionally, because the radar sensor is not physically contacting with the measured object, the sensor is almost maintenance free.
