Abstract
A guided wave radar level gauge adapted for mounting on a nozzle of a tank, including an attachment collar with an opening configured to be aligned with the nozzle and to be secured by means of an annular clamping device, and a transmission line probe attached to an exterior end of a probe connector. The GWR level gauge further comprises an annular sealing gasket fitted in the collar opening, the annular sealing gasket having a central opening through which the central probe connector extends, and a distancing sleeve arranged around the exterior end of the probe connector and having a radially protruding collar portion, wherein processing circuitry is configured to detect an impedance change caused by tank content or condensate which has passed through the central opening of the sealing gasket and collected in an annular space immediately surrounding the radially protruding collar portion.
