Abstract:
1. A guided wave radar level gauge system for determining a filling level of a product contained in a tank, which level gauge system comprises: a transceiver for transmitting electromagnetic transmission signals and receiving reflected electromagnetic signals reflected at a surface of said product; a probe, connected to said transceiver, arranged to extend vertically into said tank and configured to guide said electromagnetic transmission signals towards said surface and to guide said reflected electromagnetic signals back to said transceiver; processing circuitry connected to said transceiver and configured to determine said filing level based on said received reflected electromagnetic signals; and a plurality of spacing elements arranged on said probe, each of said spacing elements comprising: a shell structure having a substantially ellipsoidal shape defining an ellipsoidal space; a first shell opening at a first location of said shell; a second shell opening at a second location, such that a passage through said first and second shell openings defines a passage through said spherical space, wherein said probe extends through said passage; and a plurality of flow openings allowing fluid flow between the exterior and interior of said shell.
