Patent attributes
A beverage dispenser has gauges to measure the temperature of the beverage, in at least one embodiment beer, stored in a closed beverage container. The beverage is pressurized and a pressure gauge in the gas supply conduit line measures the pressure of the gas in the beverage container. A pressure regulator in the gas supply conduit line assists in ensuring that the pressure is consistent. The valve is closed during dispensation and the temperature and the gas pressure are measured immediately afterwards. By calculating the temperature change of the beverage and the pressure drop in the container, the amount of beverage can be calculated accurately. This in turn can be utilized to reliably calculate how beverage is left in the container and this information is then presented on a display, in at least one embodiment, as a series of indicator bars.
