Abstract
A sensor coupled to a computer can sense a pressure of a buffer tank. A computer can determine a start of dispensing a beverage from a beverage dispenser. The computer can determine that an elapsed time from the start of dispensing the beverage reaches a predefined duration threshold. The computer can measure a particular pressure of the buffer tank when determining that the elapsed time reaches the predefined duration threshold. The computer can determine that the particular pressure falls below a predefined pressure threshold. The computer can generate an order to replace a water filter of the beverage dispense in response to the particular pressure at the elapsed time falling below the predefined pressure threshold.
Claims20
A system, comprising:
- a sensor configured to sense a pressure of a buffer tank;
- and
- at least one computing device communicably coupled to the sensor, wherein the at least one computing device is configured to:
- determine a start of dispensing a beverage from a beverage dispenser;
- determine that an elapsed time from the start of dispensing the beverage reaches a predefined duration threshold;
- measure a particular pressure of the buffer tank when determining that the elapsed time reaches the predefined duration threshold;
- determine that the particular pressure falls below a predefined pressure threshold;
- and
- in response to the particular pressure at the elapsed time falling below the predefined pressure threshold, generate an order to replace a water filter of the beverage dispense.
A method, comprising:
- determining, via one of one or more computing devices, a start of dispensing a beverage from a beverage dispenser;
- determining, via one of the one or more computing devices, that an elapsed time from the start of dispensing the beverage reaches a predefined duration threshold;
- measuring, via one of the one or more computing devices, a particular pressure of a buffer tank when determining that the elapsed time reaches the predefined duration threshold;
- determining, via one of the one or more computing devices, that the particular pressure falls below a predefined pressure threshold;
- and
- determining, via one of the one or more computing devices, to replace a water filter of the beverage dispenser based on the particular pressure at the elapsed time falling below the predefined pressure threshold.
A system, comprising:
- a sensor configured to sense a pressure of a buffer tank;
- and
- at least one computing device communicably coupled to the sensor, wherein the at least one computing device is configured to iteratively:
- determine a respective start of dispensing a current iteration beverage from a beverage dispenser;
- determine whether a respective elapsed time from the start of dispensing the current iteration beverage reaches a predefined duration threshold;
- and
- if the respective elapsed time reaches the predefined duration threshold:
- measure a current iteration pressure of the buffer tank;
- determine whether the current iteration pressure falls below a predefined pressure threshold;
- and
- if the current iteration pressure falls below the predefined pressure threshold, determine to replace a water filter of the beverage dispense.
