performance monitoring of individual hydrocyclones using sonar-based pulp flow measurement

摘要

Apparatus features a signal processor module that responds to signals containing information about sensed sound propagating through a slurry flowing in part, including overflow pipes, of cyclones operating in parallel on a cyclone battery, and determine corresponding signaling containing information about the performance of individual cyclones based upon the signals received. The signal processor forms part of a non-invasive acoustic-based passive monitoring system having cyclones and sensors attached thereto. The signal processor module provides the corresponding signaling as output or control signaling, e.g., for controlling the cyclone battery.
