ABSTRACT:
A measuring fluid dispenser for dispensing fluids in measured quantities has a user input device for generating at least one user input signal. A flow regulator provides a known fluid output flow rate by regulating fluid flow between an input port and an output port of the regulator. A first electronic valve is responsive to electronic signals, wherein a first electronic signal positions the first electronic valve in a flow permissive state, and a second electronic signal positions the first electronic valve in a flow restrictive (i.e. interrupting) state. The first electronic valve has a first valve input in fluid communication with the regulator output and also has a first valve output in fluid communication with a fluid output port. A processing unit is communicable with the user input device and is responsive to the user input signal, and is also in electronic communication with the first electronic valve for transmitting the electronic signals to the first electronic valve.
