How to Choose Foam on Beer Detector?

Those who sell beer in kegs know about one problem: the loss of beer due to foam. It’s a shame to pour it down the sink, you can’t use it, but there’s nowhere else to put it. With beer FOB you can get rid of this concern. Let us tell you how!

How Does a Foam on Beer Detector Work? 

Every time the beer in the keg comes to an end and carbon dioxide enters the beer line, a steady foam of leftover beer forms. Unfortunately, the foam fills the entire beer line up to the beer tap. When the keg is changed, it is necessary to drain this foam and some more beer to get rid of its residue. If this is not done, the first batch of beer will foam when you pour. No customer likes to pay for air.

The FOB detector device consists of a chamber with a float. When the chamber is full of beer, the float floats up and the beer flows freely through the device. But when the beer runs out and foam enters the chamber, the float lowers and blocks the beer’s exit. Thus, the foam does not get into the beer duct. 

After the keg has been changed, you just have to pull the lever to bleed the foam out of the chamber and let it fill with beer. After this the float will float up and open the outlet – you can continue to pour beer without loss. This way, the FOB detector avoids the loss of beer when changing kegs. Pouring beer down the drain is too expensive!
