Abstract
A radar level gauge system comprising a transceiver; a multi-conductor probe comprising a first probe conductor and a second probe conductor extending together from an upper probe end to a lower probe end; a plurality of spacer arrangements distributed along the multi-conductor probe; and processing circuitry for determining the filling level. Each spacer arrangement in the plurality of spacer arrangements comprises a first spacer member configured to reflect a transmit signal as a first spacer reflection signal having a first amplitude; and a second spacer member configured to reflect the transmit signal as a second spacer reflection signal having a second amplitude. The first spacer member and the second spacer member are arranged along the multi-conductor probe so that the first and second spacer reflection signals interact to provide a combined spacer reflection signal having an amplitude lower than each of the first amplitude and the second amplitude.
