APPLICATIONS OF SONAR-BASED VF/GVF METERING TO INDUSTRIAL PROCESSING

摘要

The present invention provides a new and unique processor module that features one or more modules configured to respond to one or more input signals 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 also configured to provide one or more output signals 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 one or more output signals may be used to control the operations of the processing stage. The one or more input signals may be based at least partly on 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.
