G80 FMCW Radar Level Meter

With the design of a beam angle of 3° and a very small antenna, the best measurement results can be obtained in complex conditions with intermal components, stirring devices and compact vessels. DHE G80 FMCW radar level meter is now widely
used in pharmaceutical, chemical, food, energy and water conservancy industries for accurate level measure-ment of various media.

Measurement Principle
DHE G80 FMCW Radar Level Meter is a "top view" measurement system based on the principle of frequency modulation continuous wave (FMCW). The antenna emits the electromagnetic wave with continuously changing frequency to the medium, and then the electromagnetic waves are reflected after reaching the surface of the medium. Finally, the reflected echo is received by the antenna again.

FMCW principle:
emitting and reflecting the continuous wave

R: Highest point of level measurement

H: Total distance of level measurement

D: Distance from the highest point to the media surface

FMCW principle:

1 Transmit signal 2 Receive signal Therefore, there is a frequency difference between the transmitted signal and the received signal at any point in time:Af=k* O T, in which△t is the running time of electromagnetic wave and K is the slope of frequency modulation. △t is related to distanceD:D=△t*C/ 2, and C is the speed of light. So D can be calculated based on the measured frequency difference O F. And then determine the actual level height in the tank based on D.
