Assignee: DEKA PRODUCTS LIMITED PARTNERSHIP
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC G  F  Y | IPC F  G

Claim 6:
7. A method for operating a product dispensing system having a first ingredient and a second ingredient, the method comprising:
generating a flow feedback signal indicative of a volume of the first ingredient flowing within a line of the product dispensing system;
transmitting the flow feedback signal to a feedback controller system;
receiving the flow feedback signal at the feedback controller system;
comparing a desired flow volume to the flow feedback signal;
generating a flow control signal using a feed forward controller to establish an initial value of a flow control signal based on comparing the desired flow volume to the flow feedback signal;
transmitting the flow control signal to a variable impedance device;
operating the variable impedance device in response to the flow control signal to regulate the volume of content flowing within a line of the dispensing system;
providing a first control signal to a flow control device for controlling a supply of a first quantity of the first ingredient; and
providing a second control signal to a pump module for controlling a supply of a first quantity of the second ingredient.
