Liquid dispensing system

A method of dispensing liquid to a manufacturing process from a container including an outer container and a flexible inner container, the flexible inner container containing the liquid, the method comprising:

• providing a liquid flow passage between an interior of the inner container and the manufacturing process;
• supplying pressurized fluid in a compression space between the inner container and the outer container to dispense liquid from the inner container to the manufacturing process via the liquid flow passage;
• sensing pressure in the flow passage;
• and
• controlling the pressure in the flow passage by modulating a pressure of the pressurized fluid.

A liquid handling system comprising:

• a container including an outer container and a flexible inner container, the flexible inner container containing a liquid;
• and
• a connector attachable to the container, the connector comprising:
• a probe insertable into the inner container and having a flow passage therein;
• a pressurized fluid source coupling for interfacing with a pressurized fluid source such that the pressurized fluid source is in fluid communication with a compression space between inner walls of the outer container and the inner container for causing fluid under pressure to flow into the space between the inner walls of the outer container and the inner container to force liquid out of the inner container via the flow passage;
• a pressure sensor for sensing pressure in the flow passage;
• and
• a controller coupling for interfacing with a controller that is responsive to the pressure sensor, the controller controlling flow of the liquid in the flow passage based on a signal from the pressure sensor by modulating the pressure from the pressurized fluid source.
