ABSTRACT:
A method and apparatus for monitoring characteristics of a fluid contained in a vessel includes a pair of triangular fluid displacers suspended in the vessel. The buoyant forces acting on the fluid displacers are measured using force transducers and used to calculate fluid characteristics such as the height of the fluid in the vessel, fluid density, solute concentration, and/or the presence of fluid cascading from one section of the vessel to another.
