Abstract
An indicator providing visual information of the level of bulk material in a bin has rotatable visual members with bright and dark colored surfaces covered with a transparent lens. A actuator located within the bin is operatively coupled to the visual members to turn the visual member to an ON position exposing the bright colored surface to a person when bulk material engages the actuator and to an OFF position exposing the dark colored surface to a person when the actuator is free of bulk material whereby the person can determine the level of the bulk material in the bin. The visual members are also provided with a device that triggers a sensor that activates a remote indicator providing data as to the level of bulk material in the bin.
