Abstract
A plural component dispensing system 10 receives separate fluid components, mixes the components in a predetermined ratio, and dispenses the components as mixture. Each fluid component is supplied by a separate pump 12A, 12B to an individual variably controllable fluid regulator 14A, 14B. Each fluid component is supplied from its individual fluid regulator 14A, 14B through a flow meter 18A, 18B to a mixing device 20. The ratio of the components delivered to the mixing device 20 is controlled by the individual fluid regulators 14A, 14B based upon the flow rates measured by the flow meters 18A, 18B.
