Abstract
A radar level gauge system comprising a transceiver; a probe for guiding a transmit signal towards a product in a tank, and for returning a surface echo signal; processing circuitry for determining the filling level based on the transmit signal and the surface echo signal; and a connection arrangement for conductively connecting the probe to the tank, and for providing the transmit signal from the transceiver to the probe. The connection arrangement comprises a feed-through member to which the probe is conductively connected. The feed-through member is in conductive contact with the tank at a grounding position, and a signal conductor extends through the feed-through member from the outside of the tank to the inside of the tank. A tank coupling arrangement is arranged on the inside of the tank to electrically connect the signal conductor and the metallic portion of the tank.
