Abstract
The invention provides a system and method for proportion metering multiple fluids together that are output from different pumps. The invention further provides a system and method for batch signal metering that provides feedback on the amount of fluid that has been dispensed. The invention has applications in numerous technologies, including metering together pest control fluids, such as those used for termite control; metering lawn care fluids such as herbicide and fertilizer; blending colors used in dyes, paints and the like; personal care products such as lotions; water treatment; and other technologies in which different fluids are pumped by separate pumps and thereafter mixed together downstream of the pumps prior to being dispensed.
