    摘要： Apparatus is provided featuring a signal processor or processing module configured at least to: receive signaling containing information about the conductivity of a fluid contained, processed or flowing in a pipe, tank, cell or vessel having electrodes around the circumference of the pipe, tank, cell or vessel in an irregular configuration; and determine a scale build-up in the pipe, tank, cell or vessel using a tomographic processing technique, based at least partly on the signaling received. The signal processor module may be configured to provide corresponding signaling containing information about the scale build-up in the pipe, tank, cell or vessel using the tomographic processing technique, e.g., including where the corresponding signaling contains information about a chemical to be injected to control the scale build-up, including in a closed loop manner.

    摘要： Apparatus features a container and a transducer. The container is made of a selected material and has a container wall with a selected thickness, and configured to hold a fluid therein. The transducer is configured on the outside of the container wall, and is also configured to provide a standing wave into the fluid. The selected thickness and material of the container wall is chosen to ensure about a ½ wavelength of a desired frequency exists within the container wall, so as to substantially reduce back reflections toward the transducer due to any mismatch in acoustic impedance at the interface between the container wall and the fluid, and so as to substantially maximize the amount of energy delivered to the fluid, thus improving the operating efficiency of the apparatus.

    摘要： 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.

    摘要： 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.

    摘要： An apparatus for measuring at least one parameter associated with a fluid flowing within a pipe includes a single sheet of piezoelectric film material wrapped around at least a portion of the pipe and an array of sensors disposed at different locations on the film material. Each of the sensors provides a signal indicative of pressure within the pipe at a corresponding axial and/or circumferential location of the pipe. The sensors are selectively configurable to provide the pressure signals. The signals are processed to determine the parameter. The array of sensors is configurable in response to different criteria. The criteria includes at least one of the parameter of the fluid to be output, an input signal specifying sensors to be selected, a predetermined configuration based on the parameter to be determined, and in response to a previously determined parameter of the fluid.
