Patent ID: 8839989

Claim:
A fluid dispensing system comprising: at least one microprocessor; a micro-ingredient subsystem comprising: at least one product container configured to hold a micro-ingredient; at least one product module assembly configured to releasably engage the at least one product container; and at least one pump assembly configured to attach to the at least one product container; a control logic subsystem for converting control signals provided by the at least one microprocessor into a form usable by the micro-ingredient subsystem, wherein the control logic subsystem configured to: define a PWM drive signal having a defined voltage potential, wherein the PWM drive signal has a plurality of “on” portions and a plurality of “off” portions that define a first duty cycle for regulating, at least in part, a first flow rate of the at least one pump assembly; and pulse width modulate at least a portion of the “on” portions of the PWM drive signal to define a second duty cycle for the at least a portion of the “on” portions of the PWM drive signal, wherein the second duty cycle regulates, at least in part, a percentage of the defined voltage potential applied to the at least one pump assembly; and a plumbing/control subsystem, wherein the control logic subsystem further configured to measure a second flow generated by the plumbing/control subsystem using a flow measuring device.
