  • Gas cylinder gauge
    Patent number: 5121637
    Abstract: A gauge is described for measuring the gas pressure in high pressure gas cylinders. The gauge is mounted in the high pressure port of the cylinder valve, while gas is delivered through a lower pressure portion. The gauge comprises a cylindrical housing and a retaining nut, with the housing rotatable relative to the retaining nut. The cylindrical housing encloses a coiled bourdon tube which communicates with the gas in the cylinder and coils up or uncoils in response to changes in pressure. A viewing glass encloses a pointer and scale arrangement seated in the housing to permit the gas cylinder pressure to be displayed.
