ABSTRACT:
A proportioner apparatus is capable of proportioning and admixing at least two liquids at relatively low pressures. The proportioner apparatus has a pressurizable reservoir for each liquid and a mix reservoir. A fluid communication conduit provides fluid communication between the interior of the mix reservoir and the interior of the liquid reservoirs. The liquid reservoirs are pressurized with a pressurizing gas to cause flow from the liquid reservoirs into the mix reservoir. A discharge conduit of the mix reservoir discharges admixture therefrom. When flow ceases in the discharge conduit the flow into the mix reservoir is also stopped as by shutoff valves in the fluid communication conduit. The proportioner apparatus can also include a pump operably associated with the discharge conduit to enhance admixture flow to a pressurizable tank that holds the admixture for further downstream processing. The pressure downstream of the pump is usually higher than the pressure upstream of the pump.
