<p>Fluid storage and dispensing system comprising a pressure vessel having a moveable partition member dividing the interior into first and second variable volumes. The first variable volume has a first passage adapted for the inflow and outflow of a product fluid and the second variable volume has a second passage adapted for the inflow and outflow of a compensating gas. The system includes (1) a compensating gas line for providing compensating gas, (2) a first orifice that is installed in the compensating gas line and has an upstream side and a downstream side, (3) a compensating gas vent line connected to the compensating gas line between the second passage and the downstream side of the first orifice, and (4) a second orifice installed in the compensating gas vent line, wherein the cross-sectional flow area of the second orifice is smaller than the cross-sectional flow area of the first orifice.</p>
