disclosed are dispensing methods and systems for beverages that improve the quality of product dispensed by employing periodic recirculation of stagnant product , while reducing energy usage . the methods and systems use a recirculating pump associated with a first device that provides periodic power supply to the recirculation pump . the first device may comprise a device selected from a timer , a relay or a controller . the methods and systems may include a second device in association with the first device , and the second device senses a condition in the system and determines and measures a parameter of the condition . the second device signals the first device to periodically supply power to the recirculation pump based on the determined and measured parameter of the sensed condition . preferably , the second device senses a parameter of pressure , temperature , electric current and / or voltage and product dispense - patterns .
