发明名称 Container content level gauge apparatus
摘要 The present invention provides an apparatus for indicating the level of contents within a drum. Specifically, a user can estimate the content level of a drum from a distance. The present invention is particularly useful for hunters who can determine the level of feed remaining in an automatic deer feeder from a distance. The level is discernable by virtue of a brightly colored level indicator rod, and the contents of the drum are protected from having moisture and other debris enter into the drum through the present inventions access hole by virtue of a clear or transparent cover tube.
