Dispensed liquid volume control system

In a computerized beer dispensing system for the dispensing of a preselected quantity of beer, having a faucet means connected with a pressurized source of beer, said faucet means having a flowmeter means connected thereto to produce signals indicative of the volume of beer flowing therethrough, the improvement comprising:

• a beer tap handle for user activation of the dispensing system;
• a electronic switch means for producing signals indicative of the beer tap handle position;
• a lever means for activating the switch means, being connected to the beer tap handle, and having spring return and detent means to provide a user-desirable mechanical feedback;
• actuating means for opening and closing the faucet means;
• a programmed computer means for receiving the handle position signal to produce controlling signals for activating the actuating means to open the faucet means when the lever is pulled forward and to close the faucet means when the handle is returned, and also to receive flowmeter signals to calculate values indicative of the cumulatively dispensed quantity of beer, compare them with stored values indicative of the preselected quantities and to produce signals to activate the actuating means to close the faucet means, causing the faucet means to dispense the preselected quantity of beer.
