Abstract
The present invention relates to a device in a level gauging system comprising an antenna using radar waves to gauge a level of a surface of a fluid kept in a container. The antenna is arranged above the fluid surface and comprises a plane surface facing the fluid surface and being substantially parallel with the fluid surface. The plane surface has means for transmitting radar waves towards the fluid surface and means for receiving reflected radar waves from the fluid surface in order to gauge the fluid level. The antenna comprises a radome which at least partially covers the plane surface and is shaped such that condensed fluid is directed away from the antenna by force of gravity. A thermally insulating filling material is provided between the radome and the plane surface.
