A device for determining when the material in a grain bin or similar container has reached a predetermined level of fullness. The device includes a transparent tube having feeding tubes in communication between the transparent tube and the interior of the bin. The upper feeding tube is open at a predetermined level which may be adjusted, and the lower tube may also be set to a desired lower level of grain in the bin. Both tubes slant at approximately 45 degrees to the horizontal.
