LIQUID DISPENSING SYSTEMS WITH GAS REMOVAL AND SENSING CAPABILITIES

摘要

A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas. Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel. Presence of fluid or change in phase of flowing fluid within a fluid circuit may be sensed by comparing outputs of first and second temperature sensing elements, with one sensing element including a heater to increase temperature of the sensing element in exposure to gas but not in exposure to liquid. A system and method for fluid dispensing includes a first pressure dispense apparatus and a sensing element arranged to sense a condition correlative of approach to gas saturation of dispensed fluid, and in response to such sensed condition initiates dispensation by a second pressure dispense apparatus for combining pressure dispensed fluid flows supplied to a point of use.
