ABSTRACT:
The tank-filling system includes a manifold for coupling to tanks to be filled, a pressure transducer coupled to the manifold and a temperature transducer coupleable to at least one of the tanks. The controller receives inputs from the pressure transducer and the temperature transducer and controls a vacuum pump, a filling pump, valves for the pumps and venting valve. A computer routine executed by the controller comprises portions to cause the venting valve to open and vent the tanks, the vacuum pump to evacuate the tanks to a selected point and the fill pumps to fill the tanks at a selected pressure. The routine also comprises a portion to provide reports on the identity of the compressed gas, the number of tanks and the volume of each tank. The routine also comprises, a portion to cause the venting valve to vent the tanks, a portion to cause a predetermined number of purging cycles to be performed, a portion to cause an alarm to provide a visual and/or audible alarm in the presence of certain conditions, a portion to cause the temperature signal to be changed by a predetermined factor, portions to select the timing of the venting, evacuating and filling, a portion to enable adjustment of the software in accordance with the configuration of the valves and pumps and portions to enable selection of different fill pressures of the tanks.
