  • Gauge for monitoring the content of a propane tank
    Patent number: 5555764
    Abstract: A gauge for monitoring the propane content of a propane-containing vessel includes a platform member telescopically disposed above a base member to define an intervening region. A piston and a cylinder, interactively disposed within the intervening region upon a vertical axis form a fluid-impermeable chamber within the cylinder. A fluid is confined within the chamber and communicates by way of a conduit with a pressure-indicating device. Pressure generated upon the fluid in the chamber by virtue of the weight of a vessel resting atop the platform member is sensed, and indicated in terms of pounds of weight by the pressure-indicating device.
