Probe spacing element

A spacing element for a probe in a radar level gauge system, said spacing element comprising:

• a shell structure having a substantially ellipsoidal shape defining an ellipsoidal space;
• a first and a second shell opening of a first diameter at a first and second location of said shell, respectively, such that a passage through said first and second shell opening defines a first passage through said ellipsoidal space;
• and
• a third and a fourth shell opening of a second diameter at a third and fourth location of said shell, respectively, such that a passage through said third and a fourth shell opening defines a second passage through said ellipsoidal space, wherein said second diameter is different from said first diameter;
• and
• a plurality of flow openings allowing fluid flow between the exterior and interior of said shell.

A method for arranging a probe in a radar level gauge system, said method comprising:

• providing a probe comprising a plurality of spacing elements arranged on a portion of 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;
• and
• arranging said portion of said probe comprising said spacing elements within a pipe such that said portion of said probe is prevented from contacting an inner wall of said pipe.
