Patent ID: 7481105

Claim:
A fuel level gauge comprising: a measuring pipe including a first area and a second area and having a fuel inlet opening at one end, the measuring pipe being configured as a riser pipe and defining a measuring distance; a fuel level sensor associated with the measuring pipe and disposed in a vicinity of the fuel inlet opening, the fuel level sensor including a measurement-sensitive sensor area and configured to measure the fuel filling height in the measuring pipe; and a fuel-permeable, thin-walled enveloping element, the enveloping element surrounding the measuring pipe tightly at the first area so as to form a seal with the measuring pipe, and enclosing the second area of the measuring pipe at a predefined distance over a surface, the second area encompassing at least the fuel inlet opening and the measurement-sensitive area, the enveloping area forming a large-volume antechamber upstream from the fuel inlet opening and between an inside of the enveloping element and an outside of the measuring pipe.
