Abstract
A fluid dispensing method and apparatus particularly adapted for post-mix dispensing of a soft drink, with accurate relative proportions of carbonated water and soft drink syrup. Separate syrup and water valves are controllably turned on and off, independently, at prescribed duty cycles, to provide a prescribed mix ratio, and syrup and water flow meters monitor the instantaneous flow rates of the water and syrup to minimize the effects of any pressure variations in the initial syrup and water supplies. The apparatus is conveniently modified for use with different soft drink syrups using a separate removable personality module for each syrup, characterizing its prescribed mix ratio and its viscosity.
