  • Patent number: 9926952
    Abstract: A flow conditioner for displacing and mixing fluid flow to minimize the effects of thermal gradients on the accuracy of a transit time ultrasonic flowmeter having a first portion adapted to be disposed in the pipe and extending inward toward the center of the pipe in a downstream direction with respect to the fluid flow relative to the pipe's inner surface. The conditioner has a second portion adapted to be disposed in the pipe and in juxtaposition with the first portion. The second portion extending inward toward the center of the pipe in an upstream direction with respect to the fluid flow relative to the pipe's inner surface. An apparatus for determining fluid flow in a pipe having ultrasonic transducer sites. A method for determining fluid flow in a pipe. A method for affecting fluid flow in a pipe.

  • Patent number: 8065785
    Abstract: A method for producing a turbulence conditioner for use with an ultrasonic flow meter in a pipe having the steps of identifying an effective diameter of an aperture of the flow meter to be disposed in an opening in the pipe through which the flow meter communicates pulses of ultrasonic energy with the interior of the pipe. There is the step of building a conditioner with a pitch between openings in the conditioner which is less than the effective diameter.

  • Patent number: 7823462
    Abstract: An apparatus for determining fluid flow in a pipe includes an ultrasonic flowmeter which communicates with the interior of the pipe through at least one pair of apertures, where each aperture of the one pair of apertures has an effective diameter. The apparatus includes a turbulence conditioner disposed in the pipe having openings where the pitch between openings is a function of the effective diameter of the aperture. A turbulence conditioner for a pipe has openings and a pitch. The conditioner has walls between the openings whose thickness is a function of the pitch. The conditioner has a length which is a function of the pitch. A method for determining fluid flow in a pipe includes the steps of flowing fluid through a turbulence conditioner disposed in the pipe having openings where the pitch between openings, is made a function of an effective diameter of an aperture of an ultrasonic flowmeter which communicates with the interior of the pipe through the aperture.
