Foam on Beer Detectors (FOBs)

Foam-on-Beer Detectors (FOBs) are useful in long-draw draft beer systems and help to reduce beer waste and increase profits. 

A beer foam controller FOB (Foam-On-Beer) is a device that helps to regulate the flow of beer from a keg and prevent excess foam from forming. It works by utilizing a small plastic float ball inside a vertical chamber.

As the beer is dispensed, the float ball inside the FOB rises along with the beer level. Once the beer level inside the FOB reaches a certain height, the float ball is lifted by the incoming beer and seals a vent hole at the top of the chamber, causing the flow of beer to stop. This prevents any excess foam or gas from being dispensed and ensures that only liquid beer is poured.

When the beer level inside the FOB drops due to dispensing, the float ball drops with it, reopening the vent hole at the top of the chamber and allowing beer to flow again. This cycle repeats as beer is dispensed, helping to maintain a consistent flow rate and minimizing foam formation.

The FOB can be installed in-line between the keg and the tap, or between the keg and the CO2 regulator, depending on the specific system being used.

Every bar or restaurant that serves beer can benefit from using a beer foam controller FOB. Here are some reasons why:

Consistent beer quality: By preventing excess foam and ensuring that only liquid beer is dispensed, a FOB helps to maintain consistent beer quality and taste. This is especially important for craft beer establishments, where preserving the flavor and aroma of each beer is crucial.

Reduced waste: When beer is dispensed with excessive foam, it not only affects the taste but also results in wasted beer. A FOB helps to minimize foam formation, reducing waste and saving money in the long run.

Improved efficiency: A FOB helps to regulate the flow of beer, preventing any interruption or slow-down in service due to foam issues. This ensures that customers are served quickly and efficiently, without any delays or disruptions.

Better customer experience: With a FOB in place, customers are more likely to receive a properly poured beer with the right amount of foam, resulting in a better overall experience. This can lead to increased customer satisfaction and repeat business.

Overall, a beer foam controller FOB is a simple and effective tool that can improve beer quality, reduce waste, improve efficiency, and enhance the customer experience for any bar or restaurant that serves beer.
