<p num="1"><br/><br/><br/>Disclosed is a system and method of dispensing a selected volume of liquid. <br/>The system includes an apparatus that has a reservoir having an inlet tube and <br/>outlet tube coupled thereto, and a controller for controlling at least a <br/>portion of the apparatus. Two level sensors are positioned along the reservoir <br/>and are in communication with and controlled by the controller. The method <br/>includes steps for measuring a time a liquid level in the reservoir falls from <br/>an upper level to a lower level to calculate a flow rate. The calculation flow <br/>rate may then be used to determine and compare a dispensed volume versus the <br/>selected volume. Dispensing may then continue until the selected volume has <br/>been dispensed.<br/>
