  • Fluid flow blender and methods
    Patent number: 7530278
    Abstract: A flow blender device that includes a plurality of input flow conduits and a single output flow conduit. A variable sized orifice is positioned along at least one of the conduits for metering and controlling fluid flowing through the flow blender device. The variable sized orifice can be positioned along any of the input or output flow conduits. The flow blender device can use differential pressure measurements across the variable sized orifices to determine fluid flow rates in the flow blender device.
    Type: Grant

  • Apparatus for controlling and metering fluid flow
    Patent number: 7422028
    Abstract: A device for metering and controlling fluid flow includes a variable orifice and is configured to use a pressure sensor. The device includes a fluid flow conduit having at least one planar inner wall that extends along a portion of the fluid flow conduit length, and an element having a linear edge configured to mate with the at least one planar inner wall of the fluid flow conduit. The element is movable in a direction transverse to an axis of the conduit between an open position wherein fluid flows through the conduit and a closed position wherein the element substantially shuts off fluid flow in the conduit.
