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.
