  • Patent number: 10677624
    Abstract: The present invention provides a new and unique apparatus featuring a signal processor or processing module configured to: receive signaling containing information about a fluid flow passing through a pipe that is channelized causing flow variations in the fluid flow; and determine corresponding signaling containing information about a fluid flow characteristic of the fluid flow that depends on the flow variations caused in the fluid flow channelized, based upon the signaling received. The signal processor or processing module may be configured to provide the corresponding signaling, including where the corresponding signaling contains information about the fluid flow characteristic of the fluid flow channelized.

  • Patent number: 10394207
    Abstract: Apparatus is provided including a signal processor or signal processing module configured at least to: respond to signaling containing information about particle sizes of solids forming part of a slurry stream being fed with a common feed flow into a battery of cyclones; and determine which combinations of cyclones in the battery produce overflow that has undesirable particle size characteristics using a statistical algorithm or technique, based upon the signaling received. The signal processor or signal processing module provides corresponding signaling containing about which combinations of cyclones in the battery produce overflow that has undesirable particle size characteristics, including control signaling to control the operation of the battery, including information about certain combinations of cyclones to avoid, or preferentially to use, to minimize the total amount of coarse material having the undesirable particle size characteristics produced by the battery.

  • Patent number: 9645001
    Abstract: 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.

  • Publication number: 20110056298
    Abstract: The present invention provides new techniques for non-invasive and real-time measurement of the velocity profile of slurry flow in horizontal pipes, as well as the measurement and trending of pipe wear on slurry lines. In the first case, this information can be used to determine the approach and onset of solid deposition on the bottom of the pipe. Having this information in real time can enable operation at lower velocities or higher solids concentration or both while avoiding solids deposition or plugging and their associated operational costs. In the second case, the present invention uses a permanently or semi-permanently installed ring of conformable ultrasonic transducers clamped onto the outside of the pipe. These transducers are used to measure the thickness of the pipe under their respective locations.
