Abstract:
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.
Abstract:
A fluid monitoring apparatus, including a circuitry housing containing circuitry for processing fluid sensing signals and responsively transmitting an output, with a sensor assembly adapted for mechanical and electrical coupling to the circuitry housing. The sensor assembly includes at least one sensing member arranged to respond to a fluid species of interest in the monitored fluid, for generation of an output. The apparatus includes at least one of (A) a printed circuit board adapted to engage the circuitry housing and to mechanically couple to the sensor assembly, (B) the sensor assembly including a base and sensing element removably connected to the base by press-fit coupling elements, and (C) the sensor assembly including a base and a sensing filament connected thereto, and a filament guard to protectively circumscribe the sensing filament.

Abstract:
A fluid delivery system adapted to isolate an ampoule and/or process line during purge, including an inlet control valve connecting a source of pressurized gas to a refillable ampoule, an outlet control valve connecting the refillable ampoule to a location of use, a process control valve connecting a process line to the refillable ampoule, a process isolation valve, and a purge supply valve, e.g., a three-way purge supply valve, arranged between the process isolation valve and the process control valve. A method of purging a fluid delivery system is also disclosed, including closing a process isolation valve, connecting a process line to a refillable ampoule, supplying a purge gas through a purge supply valve, e.g., a three-way purge supply valve, and cycling open and close at least once a process control valve coupled to the process line. A manifold for use in refilling an ampoule and purging a fluid supply system is also described.
