A system includes a sensor and a computing system. The sensor is coupled to a syrup line of the beverage dispenser and is configured to measure a pressure within the line. The syrup line is coupled at a first end to a syrup bag and at a second end to a pump configured to pump syrup from the syrup bag to an outlet of the beverage dispenser. The pump is operated using pressurized gas and generates a pressure corresponding to the pressure of the gas within the syrup line when both the syrup bag is full and the outlet of the beverage dispenser is closed. The sensor transmits a measured pressure to the computing system. The computing system determines that the measured pressure is less than a threshold pressure. In response, the processor transmits an alert for display on a user device, which identifies the syrup bag for replacement.

A system, method, and device to promote a compact and direct solution for craft breweries to distribute their products via kegs instead of using stainless steel and CO2 barrels, where a polymeric barrel containing an internal plastic balloon is used. This balloon is filled with beer, and, as it is filled the internal volume of the barrel is occupied, however, the internal volume is not fully filled by the balloon with beer. When full, pressurized atmospheric air is applied, without the need for filtration, since, due to having an internal plastic balloon, atmospheric air does not meet the beer. As the beer-filled barrel is filled with air, the plastic balloon is evenly crushed from all directions. While the inner plastic bag is emptied, the internal pressure must be restored with pressurized air. In the end, there is a remnant of +2% of the total volume of the beer.
