  • Ultrasonic transducer
    Patent number: 7188526
    Abstract: An ultrasonic transducer having an effective center frequency of about 42 MHz; a bandwidth of greater than 85% at 6 dB; a spherical focus of at least 0.5 inches in water; an F4 lens; a resolution sufficient to be able to detect and separate a 0.005 inch flat-bottomed hole at 0.005 inches below surface; and a beam size of approximately 0.006–0.008 inches measured off a 1½ mm ball in water at the transducer's focal point.
    Type: Grant
    Filed: June 29, 2005
    Date of Patent: March 13, 2007
    Assignee: Battelle Energy Alliance, LLC
    Inventors: Steven C. Taylor, Nancy C. Kraft
  • Ultrasonic fluid quality sensor system
    Patent number: 6634239
    Abstract: A system for determining the composition of a multiple-component fluid and for determining linear flow comprising at least one sing-around circuit that determines the velocity of a signal in the multiple-component fluid and that is correlatable to a database for the multiple-component fluid. A system for determining flow uses two of the inventive circuits, one of which is set at an angle that is not perpendicular to the direction of flow.
    Type: Grant

  • Ultrasonic flow metering system
    Patent number: 6487916
    Abstract: A system for determining the density, flow velocity, and mass flow of a fluid comprising at least one sing-around circuit that determines the velocity of a signal in the fluid and that is correlatable to a database for the fluid. A system for determining flow velocity uses two of the inventive circuits with directional transmitters and receivers, one of which is set at an angle to the direction of flow that is different from the others.
