Abstract
A system for automatically delivering one or more precise volumes of hot water to a beverage brewer for brewing a precise amount of a beverage and also permitting variable volumes of hot water, ordinarily in conventional cup sizes, to be manually obtained, is disclosed. The system employs single resistance probe sensor circuit and control circuit in combination with a latch circuit relay to maintain one level of hot water in a heated water tank for manual draw off of variable amounts of hot water from a faucet and for displacing the hot water in the tank from the one level to a second higher level for delivery of a predetermined portion of the displaced volume of hot water to a brewing funnel for brewing a precise volume of hot beverage upon command. A selector switch permits selection of different precise volume of hot water to be delivered to the beverage brewer upon command. A washer containing a threaded collar thereon formed of an electrical insulation material is disposed on the resistance probes of the system to prevent condensate moisture from bridging from the probes to the electrically conductive tank lid to which they are mechanically fastened to cause failure of the probe control circuit.
