A cylinder-filling system includes plural manifolds, for respectively coupling to groups of product containers to be filled, each manifold being connected through suitable valving and pumps to sources of different compressed gases. Respectively connected to the manifolds are reference cylinders which are in turn connected to load cells. A processor, coupled to a touch screen display, executes a program routine which enables user selection of the gas or gas mixture to be added through each manifold, including the identity and proportions of gases in each mixture and the order in which they are to be added, a number of operating parameters including vent and evacuation pressures, number of purge cycles, purge gas, alarm levels and pump and valve operating delay times. The processor controls automatic calculation of gas mixture fill weights from mixture proportions, and controls manual or automatic filling of the containers. The processor recalculates target weights for the gases based upon a predetermined fraction of variance between original target weights and fill amounts after a settling time, and controls the rate of filling separately for each gas based on the target amount of the gas to be added.
A controller for a container filling system which includes plural conduits for respectively coupling to sources of a plurality of different compressed gases, a manifold coupled to the conduits and adapted to be coupled to plural product containers to be filled, and pumps respectively coupled between the sources and the conduits, the controller comprising:
