  • Method and apparatus for dispensing natural gas
    Patent number: 5259424
    Abstract: A supply plenum connected to a source of compressed natural gas (CNG) and a control valve assembly for selectively turning on the flow of CNG through a sonic nozzle and out through a dispensing hose assembly. Pressure and temperature transducers connected to the supply plenum measure the stagnation pressure and temperature of the CNG and the ambient temperature, and a pressure transducer fluidically connected to the vehicle tank via the dispensing hose assembly monitors the pressure of the CNG in the vehicle tank.
