Abstract
A radar level gauge system comprising a single conductor probe extending through a tubular mounting structure towards and into the product in the tank, a shielding structure radially spaced apart from the single conductor probe and extending along a top portion of the probe inside the mounting structure and past the lower end of the mounting structure, and processing circuitry connected to the transceiver for determining the filling level of the product in the tank. The shielding structure at least partly encloses the top portion of the single conductor probe, and is open in a radial direction to allow entry of the product. The shielding structure exhibits a total enclosing arc angle around the single conductor probe greater than 180° inside the tubular mounting structure, and a total enclosing arc angle around the single conductor probe that decreases with increasing distance from the lower end of the mounting structure.
