Empty keg detection for carbonated beverages
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.
1. A method for dispensing carbonated beverages from a bulk keg utilizing a sensor enabled FOB providing sensor output data used to detect peaks and troughs, trigger off of thresholds and analyze sinusoidal curves when a magnetic float is within sensing range of the sensors, thereby allowing for calculation of the float speed and acceleration.
2. The method of claim 1 , wherein determination of position and movement data is utilized for anticipatory controlled action of a tap shutoff valve.
3. An improved Foam on Beer sensor controller comprising:
a float chamber having a lower inlet opposite an upper outlet and forming a housing and an internal volume sufficient to retain a float valve;
the float valve having a magnetic target and adapted for guided movement within the internal volume so as to react to the presence of foam within the housing;
a sensor control assembly supporting one or more sensors in coordination of with the magnetic target such as to detect a position of the float and a movement of the float within the chamber.
4. The improved Foam on Beer sensor controller assembly of claim 3 , said sensors comprising magnetic flux sensors placed strategically in a non-invasive manner to obtain a non-binary representation of a location of the float.
5. The improved Foam on Beer sensor controller assembly of claim 3 , further comprising:
an analog to digital converter for obtaining discreet values indicating the polarity and magnetic flux strength and providing non-binary information to determine location, velocity and acceleration of the float moving through the canister.
6. The improved Foam on Beer sensor controller assembly of claim 4 , further comprising:
an analog to digital converter for obtaining discreet values indicating the polarity and magnetic flux strength and providing non-binary information to determine location, velocity and acceleration of the float moving through the canister.
