Claim 6:
7. A level gauge comprising:
a housing comprising a bottom wall and a side wall, a surface of the side wall provided with a first scale, and the bottom wall and the side wall enclosing a receiving cavity;
a vertical member arranged in the receiving cavity and comprising an axis which can be maintained in a vertical orientation in a natural state or held perpendicular to the bottom wall;
a perpendicular member, a center of gravity of the perpendicular member being arranged on top of the vertical member, and a plane of the perpendicular member being maintained perpendicular to the axis of the vertical member; and
a rolling member rotationally arranged on the center of gravity of the perpendicular member; wherein:
when the bottom wall is placed on a gauging surface and the axis of the vertical member is maintained in the vertical orientation, a maximum value of a value of the first scale corresponding to a highest portion of the perpendicular member in the vertical orientation and a value of the first scale corresponding to a lowest portion of the perpendicular member in the vertical orientation is an inclination angle of the gauging surface; and
when the bottom wall is placed on the gauging surface and the axis of the vertical member is maintained perpendicular to the bottom wall, if the rolling member remains at the center of gravity of the perpendicular member, then the gauging surface is level, and if the rolling member rolls, a rolling direction of the rolling member indicates an inclination direction of the gauging surface.
