ABSTRACT:
A low cost liquid proportioning and mixing device of high accuracy dispensing a solution or mixture involving volume, pressure and flow rates and including a multi-stage jet proportioning and mixing device in which any variation occurring in the designed ratio of the mixture is confined essentially to the first proportioning stage operating at a low solution ratio below 1 to 5 with the pressure of free flowing solute entering the zone of confluence for each stage and the pressure of the mixture leaving the zone of confluence being essentially equal and the outflow area of any final discharge opening is possibly less but not greater than the flow area of the conduit opening from the zone of confluence of the final stage with or without a conduit used between them, the final proportion of the solution being the multiplicand of the solution proportion of the individual stages.
