The radar level gauge system further comprises a leak indication member being movably arranged inside the hollow waveguide in such a way that a force resulting from leakage of the fluid at the sealing member causes a movement of the leak indication member when acting thereon; and the hollow waveguide is configured in such a way that the movement of the leak indication member causes a change in at least one microwave propagation characteristic of the hollow waveguide.

摘要： A radar level gauge system (1) having an antenna arrangement (3) adapted to emit microwaves towards a surface (7) of the product (6) and to receive microwaves reflected from the surface (7) The antenna arrangement (3) includes a reflector (8) and a multi band patch antenna array (9) arranged at a distance from the reflector (8) and adapted to emit electromagnetic waves to be reflected by the reflector towards the surface (6). The array (9) has first and second groups of radiator elements (19) adapted to emit electromagnetic radiation with first and second radiation footprints (14, 15), wherein the second radiation footprint (15) is substantially equal to the first radiation footprint (14), and wherein the reflector (8) has a size corresponding to the first and second radiation footprints (14, 15).According to the present invention, the reflector will be adapted to receive most of the radiation in the first and second radiation footprints. This results in an optimized antenna arrangement, where the amount of radiation energy emitted without reaching the reflector is reduced, while at the same time the full reflector size is used for both frequency bands.
