  • Method and apparatus for precisely dispensing liquids
    Patent number: 6453927
    Abstract: A method and apparatus are provided for continuously dispensing precise quantities of a liquid from a dispenser holding tank into a receiving tank. A first elastic tube permits fluid flow between the holding tank and the receiving tank and a first peristaltic pump controls the flow rate of liquid through the first elastic tube. A second elastic tube permits fluid flow between the holding tank and the receiving tank and a second peristaltic pump controls the flow rate of liquid through the second elastic tube. The flow rates through the first and second elastic tubes are independently controlled. The flow rate through the first elastic tube is maintained generally constant and at a substantially greater rate than the flow rate of the second elastic tube. The flow rate in the second elastic tube is varied to maintain a desired total flow rate into the receiving tank.
