ABSTRACT:
An apparatus and method for determining the level of material within a rotating cylindrical vessel are disclosed in which a rigid member means on the interior of the rotating vessel is fixedly secured to a rod having a longitudinal axis parallel to the rotational axis of the rotating vessel, and wherein the rod extends through one end wall of the vessle to the exterior at which it is fixedly secured to an indicator means. The rigid member means within the vessel is capable of resting at the top surface of the material within the vessel. As the level of material within the vessel is raised or lowered the rigid member means will rotate, thus causing an equal rotation of the rod and the indicator means on the exterior of the vessel. By monitoring the position of the indicator means, the level of material within the vessel can be determined.
