Abstract
A radar level gauge system, for determining a filling level of a product contained in a tank, the radar level gauge system comprising a transceiver including a signal generator for generating electromagnetic signals for transmission; a transmitter branch for transmitting the electromagnetic signals; and a receiver branch for receiving electromagnetic signals. The radar level gauge system further comprises a propagation device for allowing transmitted electromagnetic signals to propagate towards a surface of the product inside the tank, where signals are reflected, and for returning reflected electromagnetic signals back from the surface of the product; processing circuitry connected to the transceiver and configured to determine the filling level based on the reflected electromagnetic signals; power sensing circuitry connected to the transceiver and configured to determine a received power level of received electromagnetic signals; and power level adjusting circuitry provided on the transmitter branch of the transceiver, connected to the power determination circuitry, and configured to adjust a transmitted power level of the transmitted electromagnetic signals in response to the determined received power level of the reflected electromagnetic signals.
