ABSTRACT:
An apparatus is disclosed for controlling flow rates of a primary fluid including aspirating, mixing, and metering the primary fluid with a secondary fluid. In one aspect, the invention includes means for passing a secondary fluid of diluent gas through a venturi having specified proportions including discharge coefficient; and means for pumping primary fluid through venturi suction to pass through a primary fluid orifice of specified discharge coefficient wherein the venturi discharge coefficients of the venturi and the liquid orifice form a substantially linear proportionality over a wide range of flow rates through the venturi.
