Measuring principle MW-10/11 measures liquid levels by transmitting the FMCW method radar signal towards the liquid surface and receiving the echoes. As the transmission frequency is constantly changing, it is possible measure the travel time of radar signal by knowing the frequency difference between the transmission signal frequency and the received signal frequency that is reflected. The speed of radar signal and the speed of light are equally, therefore knowing the travel time of radar signal is possible measure the distance between the gauge and the surface. Upon reception, microprocessors and intelligent software in the gauge head analyzes the echoes and transform them into level output data. The radar signal is virtually less affected environment such as temperature or atmosphere pressure. Thus, radar measurement is proven to be the most reliable gauging method in the most applications.
Advanced performance The measuring principle is based on the FMCW method radar technology.
