Abstract:
A system for generating a mixture of a first fluid and a second fluid, wherein the second fluid constitutes a predetermined percentage of the ultimate mixture, said system comprising:a flow meter having an inlet in fluid communication with the first fluid, an outlet, and at least one rotatable element positioned between the inlet and the outlet, wherein said rotatable element rotates about an axis when the first fluid is directed through the inlet to the outlet, said element disposed in a housing defining top, bottom and side walls; a shaft coupled to the rotatable element; a first pump including at least one rotatable element mounted within a second housing defining a top, bottom and side walls where said bottom wall is common to the top wall of the first housing, said first pump disposed between an inlet for a second fluid and an outlet, where said rotatable element is operably coupled to said shaft such that a predetermined amount of the second fluid is pumped through the outlet of the first pump when a predetermined amount of the first fluid is directed through the inlet of the flow meter to the outlet of the flow meter where the first pump outlet is concomitant with the outlet of the flow meter; and a shaft connected to the rotatable element of the flow meter and a second pump including a first and second gear mounted within a second housing between an inlet for a third fluid and an outlet, where said first gear of said second pump is coaxially coupled to said shaft such that a predetermined amount of the third fluid is pumped through the outlet of the third pump when a predetermined amount of the first fluid is directed through the inlet of the flow meter to the outlet of the flow meter.
