<p>PURPOSE:To provide a high pressure gas filling dispenser, with which the density (pressure) and the flow of compressed gas can be measured by one measuring instrument, and by which assembly work and inspection work can be easily carried out. CONSTITUTION:A gas feeder is provided with a pressure generation unit 4 for compressing a gas into fixed pressure, and a dispenser unit 5, while a variable pressure accumulator 18 and a high pressure accumulator 19 are provided in parallel to one another on the pressure generation unit 4, and the compressed gas from multistage compressor 15 is thereby accumulated alternately. A pressure adjustment valve 24, a cut-off valve 25, and a Coriolis measuring instrument 26 are provided on the dispenser unit 5. When a feeding nozzle 31 is connected to a fuel tank and a feeding switch 34 is turned ON, the gas is fed in multistage from the variable pressure accumulator 18 and the high pressure accumulator 19, while the flow and the density of the gas fed from the Coriolis measuring instrument 26 are measured, and the pressure is calculated based on the density.</p> |
