An apparatus for determining a vertical level or density profile of a fluid column

Abstract

An apparatus for determining a vertical level or density profile of a multi-layered fluid column including at least two different liquids, the apparatus comprising: an elongate vertical support member; and a plurality of measurement modules spaced apart, and supported along, the elongate vertical support member to 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 for transmitting measurement data from the plurality of measurement modules to the data processing unit, and wherein the data processing unit is configured to process the measurement data from the plurality of measurement modules and generate a level or density profile of the fluid column.
