FOB Detectors will increase your profit by lowering your beer waste.
A FOB Detector will immediately shut down the beer flow when a keg empties. This eliminates foam and wasted beer after a keg has blown because the beer lines stay full of beer at all times.

A “Foam On Beer” Detector helps to eliminate waste in a long draw beer system. A normal beer flow supports the float at the top of the chamber. Interruption of beer flow allows the float to drop sealing the line so that the line will not fill with foam. Minimising wasted beer and saving on keg change time.
