ABSTRACT:
An apparatus for metering and feeding a solution is disclosed. The apparatus comprises a container, an inlet valve for feeding a solution into such container, and an outlet valve for allowing the solution fed into the container to flow out of the container when operated. A chamber located in the lower part of the container traps air during filing of the container at a pressure which corresponds to the hydrostatic head of solution in the container. A pressure transducer connected to the chamber provides an output signal proportional to the volume of solution in the container. A control device responsive to the output of the transducer closes the inlet valve when the predetermined volume of solution is reached and opens the outlet valve to allow discharge of the solution to the chemical process or other utilizing systems.
