Ever wonder how much beer is left in that keg of yours? It's never fun trying to guess by lifting the keg, which can sometimes shake up sediment in the bottom and cloud your beer. Never wonder again with the Ball and Keg! A very simple device, the Ball and Keg makes use of a sanitized ball on the inside of the keg and a magnetic indicator bead on the outside. First, sanitize the ball with your chosen sanitizer, and drop it into your full keg. Then, use the included magnet to locate the ball inside the keg. Once this is done, you can tilt the magnet and drop the indicator bead in its place. From then, the indicator bead will float downward as the liquid level in the keg drops, and you will be able to keep track of the liquid level in your keg. Never guess at your remaining beer levels again! Checkout the video below for more information:
