Abstract
A siphoning operation is controlled to meet a target flow rate of liquid being siphoned into a container having a headspace to which a vacuum is induced with an ejector. The incremental mass of liquid siphoned into the container is monitored and the vacuum applied to the container is continuously adjusted. A vacuum regulator responsive to an electric current-to-pressure converter which is coupled to a control unit is provided to control the flow of pressurized fluid delivered to the ejector.
