    摘要: A diagnostic method for a gas supply system (10) includes: determining a desired ramp rate for filling a vessel (24) from a supply of compressed gas (12); monitoring the actual pressure of gas entering the vessel (24); and discontinuing the flow of gas into the vessel (24) when the actual pressure deviates from the intended pressure at the desired ramp rate by an undesired amount. A system (10) for carrying out the method includes a flow controller (26) for controlling operation of the supply system (10) to deliver compressed gas from a source (12) to a vessel (24) through a supply line (22) at a desired ramp rate. The system employs a pressure monitor (34) downstream of a control valve (28) for measuring the pressure of gas directed into the vessel (24) and transmitting pressure-related data to the flow controller (26), which closes the control valve (28) to discontinue filling of the vessel (24) if the actual pressure exceeds a permissible deviation from the intended pressure.
