Abstract
An improved fluid additive system is disclosed. The first embodiment of the invention is formed by a system (10) including a controller (26) which automatically delivers a preselected quantity of a secondary fluid from a secondary container (14) at a preselected rate and subsequently delivers a preselected quantity of a primary fluid from a primary container (12) at a preselected rate. Within the controller (26) are input controls (48) for operator input of the desired preselected rates and quantity of fluid to be infused. A passive metering unit (36, 36') is provided in the controller for metering a known quantity of fluid to a delivery line upon each activation thereof. A microprocessor (40) responds to the rates amd quantity input into the input controls (48) to direct a drive unit (38) to activate the metering unit (36) to achieve the desired rates and quantity of infusion of the primary and secondary fluids.
