Abstract
The present invention relates to a guided wave radar level gauge system for determining a filling level of a product contained in a tank. The level gauge system comprises a transceiver for transmitting and receiving electromagnetic signals, a probe extending into the tank and configured to guide the signals towards the surface and to guide reflected signals back to the transceiver, processing circuitry for determining the filing level based on the reflected signals, and a plurality of spacing elements arranged on the probe. Each spacing element comprises a shell structure having an ellipsoidal shape defining an ellipsoidal space, first and second shell openings at first and second locations of the shell, such that a passage through the shell openings defines a passage through the spherical space, wherein the probe extends through the passage, and a plurality of flow openings allowing fluid flow between the exterior and interior of the shell.
