The draft beer head, wine dispenser, and liquor gun are automatic pourers designed to portion out draft beer, wine on tap, and other types of drinks stored in large containers. The pourers are connected by tubes to kegs or containers located in a separate room.
 
You can preset 4 sizes for each type of drink. Once you’ve selected a size for a type of drink, the exact quantity goes into the glass, and is displayed along with the exact price. However, if you prefer the traditional method of serving draft beer or wine on tap, you always have the option of using the system without the pourer, with the inline flowmeter. When you are done pouring the beer, the system will indicate the size poured.
