Abstract
Apparatus for indicating the level of flowable material in a storage bin comprising a motor rotatably suspended by a spring within a protective enclosure and a drive shaft coupled by a ball-and-detent clutch to a paddle disposed within the bin to engage material therein. When the material reaches the level of the paddle, the drag on the paddle causes the motor to rotate eccentrically within the enclosure and thereby to activate switches disposed within the enclosure radially of the motor housing. A spring returns the motor to the switch-deactivated position when the material level decreases and the consequent drag is removed from the paddle.
