ABSTRACT:
A liquid dispenser comprises a sprayer device and volume meter connected together to form an integral unit that prevents the sprayer device and volume meter from being disconnected without damaging the dispenser. The volume meter has an inlet end portion and a gauge member downstream of the inlet end portion that responds to liquid flowing through the dispenser to provide a visual readout indicating the volume of liquid flowing through the dispenser. A common passageway extends through the sprayer device and volume meter through which liquid flows from the inlet end portion of the volume meter, past the gauge member, and exits the sprayer device at a head end thereof.
