Abstract
A device for checking the contents of a container (5) for a supply substance (8) that is not self-leveling. The device includes a stirring blade (2) that is rotatable about an axis of rotation (D) for the delivery of the supply substance (8) to a consumer (21), for example, the suction chamber (2) of a lubricating pump, and for freeing the supply substance (8) of air inclusions, with a mechanism for scraping off the supply substance (8) from the stirring blade (2) and with a measuring unit (22) for measuring the fill level of the supply substance (8) in the container (5). The region of the container bottom (9) has openings (18) for transferring the supply substance (8) in a direction toward the consumer (21) and at least one radial stationary flank (1) is disposed, at least locally, in the region of the container center and is spaced from the container bottom (9) such that the stirring blade (2) can be at least partially rotated under the radial stationary flank.
