摘要： A method is provided for verifying integrity of a recirculation valve in a recirculation line of an LNG dispenser. The method includes: closing the recirculation valve and a fill valve in a supply line that supplies LNG; monitoring a mass of the LNG flowing through the recirculation line to ensure that the mass flowing therethrough is less than an acceptable threshold; and aborting any pending sales if the mass of the LNG flowing therethrough is not less than the acceptable threshold. According to another embodiment, a method is provided for verifying integrity of a vent valve in an LNG dispenser. The method includes: closing the vent valve and opening a fill valve in a supply line that supplies LNG; monitoring the pressure of the LNG within the fill hose to ensure that the pressure remains steady; and aborting any pending sales if the pressure does not remain steady.

摘要： According to one embodiment, a CNG dispenser is provided that includes a user-actuatable button for allowing selection of a pressure to which to fill a vehicle tank with CNG, and a controller for opening a high pressure fill valve to dispense high pressure CNG into the vehicle tank while monitoring the pressure of the vehicle tank until the pressure reaches the user-selected pressure. According to another embodiment, the controller is operable in a selected one of two modes of operation. The two modes of operation include a one-pressure bank operation mode in which only the input of a high pressure fill valve is coupled to a CNG supply line, and a three-pressure bank operation mode in which the inputs of each of three fill valves are coupled to respective CNG supply lines. A graphic fuel gage may be provided on the dispenser payment terminal screen.
