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 gas cylinder monitoring system is disclosed having a gas cylinder for receiving and distributing gas contained therein, a first monitoring system associated with the gas cylinder operable to monitor data associated with the gas cylinder and having a transmitter operable to broadcast the data at a controlled time and/or time interval in a discrete advertisement package, and a second monitoring system associated with one or more locations in which the first monitoring system may reside and having a receiver operable in a first mode to receive the advertisement package broadcast from the first monitoring system when the second monitoring system is within range of the first monitoring system.

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.

A check valve assembly includes a valve, cam and arm with float rotatably connected to the valve for insertion into a fluid storage container for filling of the container without overfilling. The valve includes a channel of narrowing diameter and restricting member movably retained within the channel. One end of the restricting member rides along the cam profile as the arm rotates the cam with the changing fluid levels. When the fluid reaches maximum fill level, the restricting member contacting the cam drops into the cam valley, driving the restricting member head into engagement with the channel neck walls and automatically sealing off the valve. First and second biasing members are disposed in the channel, preferably around the stem, and collectively provide counter force sufficient to overcome the frictional forces of the seal to open valve and move the restricting member upward.

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 present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

The invention relates to a filling level measuring device (10) for measuring the filling level in a container (2) through the wall (9) thereof by means of ultrasound, having an ultrasonic measuring head (12), a controller (20), and a fastening device (24) by means of which the filling level measuring device (10) can be fastened to the container (2) such that the ultrasonic measuring head (12) is pressed against the wall (9) of the container (2). The invention further relates to a method of operating such a filling level measuring device (10), wherein a sampling rate is used which is situation-dependent. The invention finally relates to an assembly made up of such a filling level measuring device and at least one spacer (50) which can be attached to the lower edge of a container (2) to be provided with the filling level measuring device (10).
