SYSTEM AND METHOD OF FLOW SUPPLY, MACHINE FOR PREPARING BEVERAGE, AND ALSO DATA CARRIER ON WHICH COMPUTER PROGRAM FOR IMPLEMENTING METHOD IS STORED Russian patent published in 2023 - IPC A47J31/46 A47J31/52 F04D15/02 

FIELD: production of drinks.

SUBSTANCE: group of inventions relates to a system and method for supplying a flow, to a machine for preparing a drink, as well as to a data carrier on which a computer program for implementing the method is stored. A flow delivery system for supplying and monitoring a liquid flow includes a pump, a tracking device for monitoring the flow generated by the pump, a sensing device for detecting the presence of a flow monitored by the tracking device, and a controller for determining whether the detected flow is a liquid flow or a gas flow. The controller is configured to control the pump using the first control signal, reduce the pump control signal from the first control signal to the second control signal in response to a detected flow, which may be a gas flow, thereby changing the characteristics of the pump control signal and the characteristics of the resulting flow, and determining, based on changes in said characteristics, whether the flow is a liquid flow or a gas flow.

EFFECT: preventing pump wear and providing feedback to the user.
