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.

Hygienic tank seal

A gauging instrument intended to be sealingly mounted on a nozzle of a tank, and comprising an attachment collar intended to mate with said nozzle so as to face the product in the tank, a dielectric filling member with a radially extending collar portion which abuts an outer rim of said attachment collar, and an annular spring element arranged between the outer rim the radially extending collar portion. One or several fastening elements are configured to secure the attachment collar to, and in mating relationship with, the nozzle, such that the radially extending collar portion is sandwiched between the outer rim of the attachment collar and the nozzle, and the annular spring element exerts a contact pressure on the collar portion against the nozzle to thereby ensure a process seal.

The present invention relates to reflector arrangement for proof test of a radar level gauge and to a radar level gauge system comprising such a reflector arrangement. The reflector arrangement comprises a pliable elongated member for attachment to a fixed structure in the tank; a weight attachable to the pliable elongated member; and a reflector member for reflecting an electromagnetic signal impinging on the reflector plate. The weight is configured to be coupled to the reflector member in such a way that an orientation of the weight determines an orientation of the reflector member.
