Disclosed is a level indicator (301) for determining a topology of a surface (307) of a material that is filled into a container (308), said level indicator (301) comprising an antenna device (305), a holding device (304), and a control unit (312). A radiation angle (315) of the antenna device (305) as well as a three-dimensional position of the antenna device (305) relative to the surface (307) of the material filled into the container can be adjusted by means of the control unit (312). A resulting radiating direction of the level indicator (301) can be modified by having the control device (312) control a position of the antenna device (305) and control a radiation angle and/or reception angle (315) of the antenna device (305). |
