A cylinder of pressurized fluid, including a valve assembly housing a fluid circuit including at least one shut-off valve, the cylinder being equipped with a bonnet for protecting the valve assembly including a rigid structure delimiting a protective volume around the valve assembly, including a pressure indicating device including at least one piston sensitive to the pressure in the cylinder and mobile relative to the body of the valve assembly according to the level of pressure in the cylinder between at least a retracted first position and a deployed second position, the pressure indicating device including at least one mobile information support configured to collaborate mechanically with the piston, the information support being able to move between at least two distinct positions or states to symbolize respectively at least two levels of pressure according to the position of the piston.

A sensor assembly is positioned on an exterior of a tank to measure a fluid level within the tank. The tank is modified to include a surface feature and the sensor assembly is slotted within that surface feature. The sensor assembly includes a sensor device and a control circuit configured to drive the sensor device and evaluate readings to determine the fluid level. The sensor assembly further includes a communications interface to enable communication with a management system via a communications network. The management system can store information (e.g. fill status) related to the tank and additionally communicate with vendors or end users to coordinate resupply.

Provided is a handle assembly for a cylinder. The handle assembly includes a shroud configured to attach to a collar of the cylinder to surround a valve port of the cylinder, the shroud having a first plurality of circumferentially spaced deflectable fingers extending downward in a first direction, and a second plurality of circumferentially spaced deflectable fingers extending upward in a second direction, and a handle configured to attach to the shroud, the handle having a body configured to surround and abut the shroud, and a first plurality of circumferentially spaced openings extending through the body. The first plurality of circumferentially spaced deflectable fingers are deflectable to engage respective openings in the collar to attach the shroud to the collar, and the second plurality of circumferentially spaced deflectable fingers are deflectable to engage a respective one of the first plurality of circumferentially spaced openings in the handle.

The pressure vessel contains a fluid, such as a high pressure gas, therein. The metal dome and the metal dome are arranged in the longitudinal direction of the pressure vessel opposite each other with the pressure vessel interposed therebetween. The stay connects the metal dome and the metal dome. The stay is connected to the metal dome and the metal dome such that the distance between the metal dome and the metal dome can be varied.

A method for calculating the autonomy of a gas distribution system assembly including a container containing gas and equipped with at least one gas filling indicator device and a gas flow rate indicator device at the output of the container. The method includes recovering at least one item of identification information on the container and/or the gas used. The method also includes acquiring at least one image to recover a first datum on a value indicated by the gas filling indicator device and a second datum on a value indicated by the flow rate indicator device. The method also includes communicating the at least one acquired image and the at least one recovered tern of identification to a computation module configured to deduce therefrom a corresponding value of autonomy of the gas distribution assembly, the computation module including at least the ability to process images.

Provided is a handle assembly for a cylinder. The handle assembly includes a shroud configured to attach to a collar of the cylinder to surround a valve port of the cylinder, the shroud having a first plurality of circumferentially spaced deflectable fingers extending downward in a first direction, and a second plurality of circumferentially spaced deflectable fingers extending upward in a second direction, and a handle configured to attach to the shroud, the handle having a body configured to surround and abut the shroud, and a first plurality of circumferentially spaced openings extending through the body. The first plurality of circumferentially spaced deflectable fingers are deflectable to engage respective openings in the collar to attach the shroud to the collar, and the second plurality of circumferentially spaced deflectable fingers are deflectable to engage a respective one of the first plurality of circumferentially spaced openings in the handle.

A fully removable chime or valve guard that can support the container on its top, side and bottom is provided. The removable chime or valve guard provides protection if the container is dropped on its side or top. The protection provided allows the containers to pass a drop test per 49 CFR section 178.603, so the containers can be certified per 49 CFR 178.504.

Provided is a handle assembly for a cylinder. The handle assembly includes a shroud configured to attach to a collar of the cylinder to partially surround a valve port of the cylinder, the shroud having a body with first and second ends circumferentially spaced from one another to define a gap through which a valve is configured to extend, and a plurality of circumferentially spaced locking protrusions projecting from the body, and a handle configured to attach to the shroud, the handle having a body defining a channel for receiving the shroud, and first and second ends circumferentially spaced from one another to define a gap through which the valve is configured to extend, wherein the channel includes a plurality of openings in a wall thereof through which the locking protrusions extend when the handle is attached to the shroud to secure the handle to the shroud.

An object of the present invention is to provide a gas storage container that is easy to transport and install. The gas storage container according to the present invention has flat upper and lower surfaces and can be stacked vertically. The gas storage container according to the present invention may include a casing that has a flat upper surface and a flat lower surface and is vertically stackable, and a gas container installed in the casing.

A gas cylinder monitoring system comprising a gas cylinder for receiving and distributing gas. A flow control valve is associated with the gas cylinder and operable to allow or prevent the flow of gas from the cylinder. A monitor is provided for monitoring a signal from an input device associated with the flow control valve. The monitor has an environmental parameter sensor for detecting the presence or absence of a selected environmental parameter in the vicinity of the cylinder. The environmental parameter sensor is connected to the monitor for transmitting an environmental status signal thereto. A removable cover is provided for covering both the flow control valve and the environmental parameter sensor such as to only allow access to the flow control valve when the cover is removed. A transmitter is also provided for transmitting a signal, obtained by the monitor from the input device, to a receiver.
