Balanced system
From Home Brewing Wiki
The term Balanced System refers to a kegging system in which the serving pressure is allowed to dissipate as the beer is dispensed, thus preventing foaming. A balanced system is typically achieved through the length and thickness of the beverage lines; longer or narrower lines aid in reducing the pressure as the beer is dispensed.
A balanced system allows the brewer to set the regulator to the desired pressure for carbonation without having to make adjustments for serving.
