Abstract
A device in which the quantity of particles stored in a container is monitored. The device is arranged to indicate when the supply of particles is beneath a predetermined level. A shaft member positioned in the particle storage container is rotated from a first position to a second position. When the level of particles therein is beneath the predetermined level, a magnetic torque overcomes the resistance offered by the particles to rotate the shaft from the first position to the second position indicating that additional particles should be added to the storage container.
