A pressurized fluid container having a pressure indicator device, the device having-a piston sensitive to the prevailing pressure in the pressurized fluid container, the piston moving, depending on the value of the pressure in the pressurized fluid container, between at least a retracted position and a deployed position; an indicator component configured to cooperate with the piston, the indicator component moving, depending on the position of the piston, between at least a first position representing a first pressure value and a second position representing a second pressure value.

Pressurized-fluid container with a pressure indicator device

A device for supplying pressurized fluid including a pressurized fluid cylinder, at least one first tap connected to the pressurized fluid cylinder, the tap including an internal fluid circuit including an isolation valve, the device including an electronic apparatus for the wireless remote communication of data via electromagnetic waves, the electronic communication apparatus including a communication element designed to communicate wirelessly using at least one of the following frequency-modulation and/or phase-modulation low-consumption and long-range communication technologies: LoRa communication technology, communication technology from Sigfox, where the device includes a protective cap mounted on the cylinder in order to protect the first tap and a second tap connected detachably to the first tap, and the electronic communication apparatus being situated either on the cylinder, on the cap, on the first tap, or on the second tap.

Device for providing fluid under pressure

The invention relates to a device including: at least one fluid-using apparatus; at least one movable tank capable of and intended for providing at least the fluid and connected, via pipes, to the fluid using apparatus, the movable tank containing, at the outset, a given initial amount of the gas; and a means for assessing amounts of the fluid that are used by the fluid using apparatus from the movable tank, the assessment means being rigidly connected to the fluid-using apparatus.

Method and device for tracking content of a movable fluid tank

Device for feeding fuel gas to an application (), the device comprising at least one fuel gas bottle () furnished with a tap (), and a bleed-off apparatus () comprising an electronic logic unit () and a bleed-off outlet () selectively connectable to the tap (), the bleed-off outlet () being linked () fluidically to an application () receiving the fuel gas originating from the bottle (), the tap () comprising an electronic manometer () for measuring the pressure in the bottle (), the electronic manometer () being devoid of battery and comprising an inductive member () for wirelessly transmitting to the electronic logic unit () information relating to the measured pressure, characterized in that the bleed-off apparatus () also comprises an inductive member () powered electrically by the electronic logic unit () and in that, when the bleed-off outlet () is connected up to the tap (), the inductive member () of the bleed-off outlet () is situated in a manner adjacent to the inductive member () of the manometer () so as to ensure electrical power supply of the manometer () by inductive coupling.

Device for feeding fuel gas to an application

The device (,) for controlling an installation (,) comprising means (,, for monitoring and/or commanding the operation of the installation (,), and a central data processing unit (,) adapted to communicate with the means for monitoring and/or commanding (,) for reading, sending and/or processing the data concerning the operation of the installation. The central unit (,) comprises memory means (,) for storing at least one parameterized task acting on said data concerning the operation of the installation, memory means storing at least one table, each table being associated with a parameterized task and comprising values of parameters of the considered task, for executing the latter, and, connected to each memory means (,), means (,) for executing said parameterized tasks by using said values stored in said table or tables when executing said parameterized tasks.

Device for controlling an installation having memory for storing plurality of parameterized tasks acting on data concerning the operation of the installation
