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.

The invention relates to a pressurized gas container, in particular a gas cylinder, having an internal volume for gas storage, a fluid-distributing valve, a pressure sensor and microprocessor-based control means. The microprocessor-based control means are configured to detect filling of the gas container with gas, by comparing said at least one pressure value measured by the pressure sensor with at least one predefined and stored reference pressure threshold value; then to initiate a timer on the basis of a detection of filling of the gas container with gas; and to trigger a warning when the timer exceeds a given period calculated from the initiation of the timer.

The invention pertains generally to a handle which spans across two cylinders, each cylinder having a pair of collars, in which mating engagement is secured by various fastening approaches employing the peripheral ends of each handle.

The invention relates to a gas container having a gas distribution valve and an electronic measurement device arranged on the gas distribution valve. The electronic measurement device having an electronic display screen which is electrically connected, via an electrical connecting connector, to a circuit board having at least one microprocessor. The electrical connecting connector having a connector body in the shape of an elongate bar through which a plurality of electrically conductive elements passes extending between two opposite faces of the connector body. The electrically conductive elements are separated from one another by regions made of insulating material.

A valve for pressurized fluid housing a fluid circuit having an upstream end and a downstream end and a valve for controlling the flow rate in the circuit that is controlled by a movable actuating member in order to control the opening or the closing, the valve having a lower end provided with movable coupling member(s) intended to cooperate with one or more complementary coupling members on a gas source or a circuit, the valve further comprising a member for locking the coupling member(s) that is mounted movably on the body of the valve between a first position not blocking the movement of the coupling member(s) and a second position blocking the movement of the coupling member(s).

The innovation described herein generally pertains to a system and method related to a pressure vessel including a tank formed of an injected tank liner with co-injected boss and permeation barrier film surrounded by a layer of thermoplastic composite filament winding and a protective jacket disposed thereon that facilitates stacking and portability of the pressure vessel and provides an air passage for convective heat transfer between the tank and the environment.

A gas cylinder mobility aid is provided. A gas cylinder mobility aid for attachment to a collar of a gas cylinder, comprising a base plate having an upper surface and a lower surface. One or more coupling members affixed to the lower surface of the base plate wherein the one or more coupling members are positioned to form a frictional fit with the collar of the gas cylinder. A vertical member affixed at the center of said base plate and a handle rotatably attached to the vertical member such that the handle is present above the upper surface of the base plate and the handle rotates about the vertical member.

Provided is a portable cylinder including a tank having an upper portion having a valve port, a mounting collar coupled to the upper portion of the tank, and a handle attached to the mounting collar. The mounting collar has an upwardly extending portion surrounding the valve port and a plurality of circumferentially spaced tabs extending radially outwardly from the upwardly extending portion, wherein a respective gap is formed between adjacent ones of the plurality of circumferentially spaced tabs. The handle includes a shroud portion including a plurality of circumferentially spaced ledges for abutting an underside of a respective one of the plurality of circumferentially spaced tabs, and at least one tab for engaging the mounting collar in one of the gaps, and a handle portion extending from the shroud portion and having one or more areas for grasping the handle.
