Abstract
A hand-powered apparatus and method for measuring and dispensing a predetermined volume of liquid. A predetermined volume of liquid is selected using a control knob on the apparatus and a valve is moved to a fill position. The handle on an attached hand pump is then moved alternately up and down causing fluid to be drawn into a measuring vessel. Further upward movement of the handle is prevented upon the fluid level in the vessel reaching the selected volume. Thereupon, the valve is moved to a dispense position whereby continued pumping of the handle is again possible. The handle is alternately pumped up and down causing the fluid to exit the vessel.
