ABSTRACT:
Apparatus for indicating the level of flowable material in a storage bin that includes a motor mounted within a protective enclosure and coupled by a shaft and clutch arrangement to a paddle disposed within the bin to engage material therewithin. When the material reaches the level of the paddle, drag on the paddle causes the motor to rotate within the enclosure against the force of an adjustable spring to activate switches disposed within the enclosure for indicating material level. The switches also remove power from the motor and apply power to an electrical resistance heater to warm the enclosure and help prevent condensation at low external ambient temperature. The paddle is constructed to enhance drag when used in conjunction with low-density materials.
