ABSTRACT:
A radar level gauge system is disclosed, comprising: a transmitter for transmitting pulsed measuring signals into a tank; a receiver for receiving echo signals from the tank; and processing circuitry for processing the received echo signals, said processing means including an amplifier for amplification of the received echo signals. Further, the amplifier is operable in a high and a low amplification mode, and the processing circuitry is arranged to control the amplifier intermittently in order to be in the high amplification mode only during certain time slots. By intermittently operating the amplifier in a low amplification mode, providing only a low or moderate amplification, or preferably being shut off (i.e. with essentially no amplification), the power required for the amplification could be significantly reduced. Further, the noise generated by the amplifier could be significantly reduced.A corresponding processing circuitry and operating method are also disclosed.
