  • Patent number: 9921092
    Abstract: A method for determining one or more fluid flow parameters for a fluid flowing within a pipe is provided. The fluid is a mixture of solid particles and gas. The method includes the steps of: a) providing a meter operable to determine the velocity of the fluid flow through the pipe, which meter is substantially insensitive to the particulate/gas mass ratio of the fluid flow; b) determining the velocity of the fluid flow within the pipe using the meter; and c) determining a particulate/gas mass ratio using a density value for the gas within the flow and the determined fluid flow velocity.

  • Patent number: 9851201
    Abstract: New techniques are provided for measuring the thickness of a pipe wall using ultrasonic reflections. The apparatus includes a signal processor that receives a signal containing information about ultrasonic pulses injected into a pipe wall; and determines a pipe wall thickness measurement based at least partly on decomposing the signal received in order to identify either peaks using a cepstrum analysis or repeated spacing using a wavelet analysis. The wavelet analysis includes dividing data in the signal received into a specific frequency component and a defined temporal component in order to detect correct pulses where multiple reflections are caused by irregularities in the pipe wall surface being measured. The cepstrum analysis includes processing repeating pulses in the signal in order to detect correct pulses where multiple reflections are caused by irregularities in the pipe wall surface being measured.

  • Patent number: 9833763
    Abstract: 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.

  • Patent number: 9404893
    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.
