Abstract
A processor module features a module that respond to input signalling containing information about a volumetric flow of a fluid having minerals and varying amounts of entrained gas flowing in a pipe and being processed in a processing stage of a mineral extraction processing system for extracting a mineral from ore, and provides output signalling containing information about operations of the processing stage of the mineral extraction processing system that is not substantially affected by the varying amounts of entrained gas in the fluid flowing in the pipe. The output signalling controls the operations of the processing stage. The input signalling is based upon a speed of sound measurement, including a SONAR-based entrained gas measurement to determine the amount of entrained air in conjunction with a density measurement of the fluid flowing in the pipe.
