What does the acronym FOB stand for in beer dispensing systems?

The acronym FOB in beer dispensing systems stands for "Foam On Beer." This term refers to a device that is designed to prevent beer from being wasted due to excessive foaming in the lines during dispensing. A FOB system works by detecting the presence of foam in the beer lines, which can occur due to various factors such as pressure fluctuations, temperature changes, or improper pouring techniques.

When foam is detected, the FOB system automatically closes a valve to stop the beer flow until the foam dissipates, ensuring that only liquid beer is served. This reduces waste and maintains the quality of the beer being dispensed, as excessive foam can lead to inconsistent pours and a negative customer experience. By controlling foam, operators can provide a better service and ensure that they are getting the most out of their beer kegs.
