Measured liquid dispensing system

Abstract

A measured dispensing system includes a bulk reservoir containing a bulk quantity of a liquid material and a measurement container interconnected with the bulk reservoir. A pressure sensor is received within the measurement container for sensing a pressure head which develops therein as liquid is caused to enter the measurement container. Additionally, the measurement container has a level sensor therein for sensing the presence and absence of the liquid material in the measurement container at a particular level. A microprocessor controls valves allowing liquid to enter the tank during a filling cycle to determine when a specific quantity of the liquid has been received therein. The microprocessor similarly controls a dispensing valve and monitors a low level sensor to determine when that quantity has been dispensed from the tank.
