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. An electronic control system connected to the pressure and temperature transducers and to the control valve assembly calculates a vehicle tank cut-off pressure based on the ambient temperature and on the pressure rating of the vehicle tank that has been pre-programmed into the electronic control system, calculates the volume of the vehicle tank and the additional mass of CNG required to increase the tank pressure to the cut-off pressure, and automatically turns off the CNG flow when the additional mass has been dispensed into the vehicle tank. The electronic control system also determines the amount of CNG dispensed through the sonic nozzle based on the upstream stagnation temperature and pressure of the CNG and the length of time the CNG was flowing through the sonic nozzle.
