  • Patent number: 11673787
    Abstract: A system and method detection of an empty keg is provided. Carbonated beverages from a keg communicates a carbonated alcoholic beverage to a Foam on Beer (FOB) detector. The FOB forms a reservoir and containing a float. Level detection sensors in operative communication with the float identifies the position and movement of the float. An keg's status can thereby be anticipated by float level and speed changes. A the FOB status can thereby operate a touchless tap including a control valve via a tap control board (TCB) that actuates the control valve. A controller in operative communication with the TCB communicates with the control valve, the actuation button and in communication with the level sensor.

  • Patent number: 11613455
    Abstract: An automated system for venting gas from a FOB is provided replacing a conventional manual venting button at the top of a FOB with a remotely controlled vent (bleed) valve attached to the FOB. After that the venting button is reinstalled in parallel with the vent valve. The automated vent valve can be implemented as a solenoid or pneumatic valve and is controlled by a controller. A tube connects FOB's vent outlet with a waste bucket. When the FOB is vented, a mix of gas, foam, and beverage is expelled from the FOB chamber and deposited in this waste bucket.

  • Patent number: 11472694
    Abstract: A system and method detection of an empty keg is provided. Carbonated beverages from a keg communicates a carbonated alcoholic beverage to a liquid beverage sensor in fluid communication with the bulk keg. The liquid beverage sensor includes at least one phase detection sensor capable of identifying a foam or gas-liquid interface (Float on Beer Detector), at least one pressure sensor, at least one flow sensor, or at least one temperature sensor. A controller in operative communication with the TCB communicates with the control valve, the actuation button and in communication with the sensors. Upon detection of a low float level for the FOB detector, or low system pressure, or high system temperature, an alarm and/or override of the control of the tap is accomplished.

  • Patent number: 11293794
    Abstract: A thermal flow sensor is provide for beverage metering using a heater in physical and thermal communication the beverage dispensing conduit. A temperature sensing element is positioned distant from and downstream from said heater along said direction of fluid flow. A computing device controls the heater and the temperature sensing element and computes a cumulative total volume during a metering cycle. The computing of a cumulative total volume during a metering cycle may be adapted or approximated to account for residual changes in temperature of the conduit or thermal sensing element metering cycles. Flow measurement is thereby without direct physical contact with the beverage itself, thereby providing cleanable fluid paths within the beverage conduit that limits or eliminate voids or trapped volumes. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

  • Patent number: 11161730
    Abstract: A beverage dispensing system provides a product metering system, a dispenser and a control system for operatively controlling dispensing, metering, delivering and reporting of dispensed product. Authentication, authorization and control operation are distributed in a cloud based control through a wide area network. The dispenser includes sensor to identifying objects and filter out movements that are not interpreted as requests for dispensing. A local controller operates the metering and dispensing, combining inputs from the hardware level sensors and applying logic and rules from the remote cloud level. The instant abstract neither defines the invention disclosed in this specification nor limits the invention scope in any way.

  • Patent number: 11124406
    Abstract: A dispensing and pour control system for a regulated beverage having a metering system that provides a discharge in a controlled and metered manner. A sensor system uses a Line Control Board (LCB) that detects a piston location inside a metering conduit. A plurality of magnetic sensors is positioned at equal intervals and in the same plane collinear with the movement of a magnetic piston within the metering mechanism conduit. The piston position is detected by obtaining a set of momentary readings of the magnetic sensors and estimating a location of the piston by interpolation of the piston position as an anticipate location between sensors that are adjacent and showing readings of opposing signs.
