Abstract: 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.

Abstract: A beverage dispenser includes beverage temperature measurement means for measuring a temperature of beverage stored in a closed beverage container; pressure measurement means disposed in a gas supply conduit supplying gas into the beverage container from a source of pressurized gas for measuring a gas pressure in the beverage container; a pressure regulator valve disposed in the gas supply conduit for regulating a pressure of gas supplied to the beverage container; discharge means for discharging an amount of beverage supplied thereto from a beverage supply conduit connected to the beverage container; wherein the pressure regulator valve is opened and closed in such a manner that the gas pressure in the container becomes a proper pressure calculated in accordance with a temperature of the beverage measured by the temperature measurement means, wherein the beverage dispenser further comprises gas flow measurement means disposed in the gas supply conduit at a downstream of the pressure regulator valve for measu

Abstract: A first operation of a lever causes a valve rod to retract axially through a second valve element seated on a second valve seat against a first resilient part, while a first valve element to leave a first valve seat open to pour beer from a beer pouring nozzle through a beer supply channel. A second operation of the lever causes a slider to advance axially against a second resilient part to be spaced away from the valve rod forcing the first valve element to be seated on the first valve seat, while the second valve element to leave the second valve seat open to effect frothing of the beer from a liquid passage and pour the resulting froth through holes defined in a sleeve.
