Restaurants, Bars, and even home use can benefit from the Remote Keg Remainder invention. How many times have people been sitting at a bar, ordering their favorite beer just to have it start spurting out foam because the keg has been emptied. The bartender has no way of knowing how much is left in the keg, therefore not knowing that it should be replaced before the afternoon rush.
The beer in the keg has a specific weight, and the weight of the keg itself doesn't change. Therefore a scale connected to an app on any phone could show how many pints are left. The keg will sit on a scale that can be wirelessly connected to any mobile device.
Many people will benefit from this device.
