ABSTRACT:
A radar level gauge (RLG), intended for measuring with a close-range low-power radar a distance to a content surface in a container relatively to a measuring position, which is located above the surface and fixed in relation to a lower boundary of said container. The RLG comprises a transmitter for transmitting an electromagnetic transmitter pulse, a signal medium interface connectable to means for directing said transmitter pulse towards said surface and for receiving a reception pulse reflected back from said surface, and a receiver for receiving said reception pulse. A switch connects said signal medium interface to said transmitter while said transmitter pulse is transmitted, and said signal medium interface to said receiver while said reflected pulse is received, the switch having a switching time short enough to enable short distance detection.According to this design, signal losses can be reduced significantly compared to prior solutions.
