Abstract:
1. A fluid supply system comprising: a liner-based fluid storage and dispensing package including a liner adapted to contain a liquid medium in a zero or near-zero headspace conformation; a pressurizing element adapted to exteriorly exert pressure on the liner for pressure-mediated dispensing of said liquid medium from the liner; and an empty detect sensor arranged downstream of the liner to monitor sense the liquid medium dispensed from the liner in a zero or near-zero headspace conformation during said pressure-mediated dispensing and to generate an output signal alerting to a near-empty condition of said liquid medium in the liner before the liner is exhausted of the liquid medium and before any gas is dispensed from the liner, wherein the empty detect sensor comprises at least one of: (a) a pressure switch or pressure transducer adapted to monitor pressure of liquid medium dispensed from the liner to detect pressure droop or decay, and (b) an integrated flowmeter arranged to monitor flow rate of liquid medium dispensed from the liner.
