摘要： A method and system for monitoring a level of liquid fuel in a tank having a known capacity, wherein the tank fluidly communicates with a fuel supply line through which the fuel is delivered in gaseous form. The method comprises measuring a flow rate of gaseous fuel flowing through the supply line, calculating an expended fuel volume based on the measured flow rate, and determining a remaining liquid fuel level in the tank based on the expended fuel volume and tank capacity. A delivery of liquid fuel to the tank is prompted in response to the remaining liquid fuel level.

摘要： A fail safe retaining plug assembly for a slam-shut safety device includes a reset pin, a retaining plug attached to the reset pin at a proximal portion, and a safety disk attached to the reset pin at a distal portion. The retaining plug assembly is sufficiently long to prevent the safety disk from falling off of the distal portion before the safety disk contacts a valve seat. The retaining plug assembly is also sufficiently long to prevent the retaining plug from falling off of the reset pin before the safety disk contacts the valve seat.

摘要： An adapter for use with a fluid metering device includes a support structure which holds and supports the fluid metering device in an upright position while the fluid metering device is being tested with a testing device or a prover. The adapter also includes a fluid passageway having one end thereof coupled to the fluid inlet of the fluid metering device and having another end thereof positioned at a predetermined distance away from, and at a predetermined orientation with respect to, the fluid outlet of the fluid metering device to thereby enable a standard prover to be used with a fluid metering device having a non-standard inlet and outlet configuration.

摘要： A metallic gas pressure regulator includes a spring casing and a lower casing, sandwiching a diaphragm. The lower casing has axially aligned inlet and outlet ports. A one piece plastic cam stem and relief seat is mounted for movement with the diaphragm and includes a cam surface engaging a movable plastic disk holder. The disk holder is movable within a plastic orifice tube that supports a plastic valve seat. The orifice tube has a removable plastic boost end cap for providing a boost action to the diaphragm. A pressure relief mechanism is incorporated within the upper portion of the diaphragm. A metal disk is affixed in the inlet and includes a flow restricting hole and a flow diverter for directing flow toward the pressure relief mechanism in the event of destruction of the plastic orifice tube.

摘要： A drop compensated pressure regulator includes a spring casing, housing a regulator spring and a relief spring, a lower casing and a diaphragm sandwiched between the two casings. The lower casing has inlet and outlet ports. A one piece cam stem and relief seat is mounted for movement with the diaphragm and includes a cam surface that engages a movable disk holder. The disk holder is movable in a straight line within an orifice tube that supports a valve seat. A cylindrical lower spring seat is coupled by an O ring to the inner wall of the spring casing to dampen vibrations. The cam stem has built in stops to retain it within the orifice tube.
