Abstract
A unique method is being developed to indirectly measure the mass of liquid in a tank. This method (the Bob Displacement Technique), which is based on Archimedes Buoyancy Principle, is described. The working equation is developed and reduced to a linear response equation which is unaffected by density. A prototype design for use on a plutonium/uranium nitrate feed tank has been developed and is described. The water testing of this hardware is discussed. Typical fuel cycle applications and the material accountability considerations are included.
