  • Patent number: 6443609
    Abstract: An apparatus for mixing fluids includes a housing which is mounted in line with a conduit carrying a primary fluid. A deformable member is mounted in the housing and an inlet conduit carrying a secondary fluid communicates with the deformable member. An adjustment knob adjusts the width of the deformable member, thereby adjusting the venturi effect created by the deformable member in the flow of primary fluid and adjusting the flow of secondary fluid which flows into the deformable member and is induced out of the deformable member through a plurality of holes to mix with the primary fluid. A system is provided with the fluid inductor apparatus and includes a sensor at the fluid outlet to generate a signal to control the geometric profile of the deformable member to adjust mixing of the fluids.
