Abstract
Accurate, contact-free measurement, outside the processing area, of the quantity of solid material in a centrifuge cylinder used in reprocessing nuclear fuel solutions. A mechanical vibration system consisting of the centrifuge cylinder and of a supplemental mass attached to the cylinder produces torsional vibrations by, for example, increasing or decreasing the speed of the cylinder drive shaft. The frequency of the vibrations reflect the quantity of solid material in the cylinder. A sensor senses the frequency of the vibrations and sends signals to a means for computing the quantity of the load from the frequency.
