You are using a beer dispenser and you have problems with the foam when tapping? Then you have certainly set an incorrect pressure.
The correct pressure, for a perfectly tapped beer, is different for each dispenser and depends on several factors.
First of all, on the type of beer you tap. For example, the so-called saturation pressure is different for a pils beer than for a wheat beer. Other factors are the beer temperature and the design of the beer line.
With the app DRAFTBUDDY you can easily calculate the right pressure for your tap and never again have problems with too much or too little foam when tapping your favorite beer.
