Abstract: An apparatus for determining a vertical level or density of a material column including one or more of a granular solid, a wet granular solid, a slurry, and a suspension, the apparatus having a support member; and at least one measurement module, wherein the measurement module includes a support arm mounted to the support member and extending outwardly from the support member; a displacer mounted to the support arm, and a force measurement device configured to measure a force attributable to a mass of the displacer mediated by a buoyancy of the displacer in the material column, wherein the measurement module has a data connection to a data processing unit for transmitting measurement data from the measurement module to the data processing unit to generate level or density information about the material column.

Abstract: Provided herein is an apparatus for determining a vertical density profile of a multi-layered fluid column including at least two different liquids, the apparatus comprising a plurality of measurement modules that form a vertical array of measurement modules; wherein each measurement module comprises: a support arm mounted to the elongate vertical support member and extending outwardly from the elongate vertical support member; a displacer carried on the support arm; and a force measurement device configured to measure a force attributable to a mass of the displacer mediated by a buoyancy of the displacer in the fluid column, wherein the plurality of measurement modules have a data connection to a data processing unit that is configured to process the measurement data from the plurality of measurement modules and generate a level or density profile of the fluid column.
