Abstract: A device for sensing information relating to the fill level of a container storing fluid, the container being equipped with a fill- and/or discharge line and a fill- and/or discharge fitting provided therein, is equipped with: a microphone positioned on the fill- and/or discharge line, for sensing an acoustic signal as the fluid passes through said fill- and/or discharge line; means for transmitting the acoustic signals sensed by the microphone to an evaluation unit; and an evaluation unit. The evaluation unit has a memory unit storing a characteristic curve containing information relating to the modification of a characteristic parameter according to the container contents, a computer unit determining a characteristic parameter from the acoustic signal sensed by the microphone, a comparison unit comparing the characteristic parameter and identifying information concerning the container contents, and a display unit which visually displays the information relating to the container contents.

Abstract: Mobile supply systems are used to supply clients with a fluid, in which a transport container and a fluid pump for discharging the transport container into a client's container or a client's pipeline system are mounted on a tanker truck. The fluid pumps are usually fitted with hydraulic or electrical drive and are supplied with energy from the drive assembly of the tanker vehicle during the discharging process. In order to lower noise emissions at the target location caused by the discharging process, according to the invention, an electrical pump drive is used which is supplied with power at least optionally from an accumulator. The charging of the accumulator occurs by means of the drive assembly of the tanker vehicle, but independently of the discharging process, and can occur, in particular, during travel and/or outside of the target location.

Abstract: Protective devices for pressurized gas cylinders have a housing which is arranged around an inner cavity intended for receiving an extraction valve and which has access openings for the extraction connection and for further fittings. In order to counteract soiling or contamination of the extraction connection, the invention provides for an elastically deformable safety element to be fastened to the housing in the region of the access opening of the extraction connection, said element being able to be swung out from a closed position, in which the extraction connection is completely covered and/or enclosed by the safety element, into a position in which it frees the extraction connection.

Abstract: Pressurized gas bottles with integrated valves, in which a plurality of functional supports are integrated in an extraction unit, are equipped with complex fall protection means. Moreover, in such a valve, a new approval procedure is carried out for the entire valve in the event of multiple modifications, for example when supplementing it with an additional function. In order to reduce the effort associated with this, an extraction fitting for a pressurized gas bottle is provided with a modular design, wherein a base module comprising the shut-off member and a fall protection device securing the shut-off member complies with legal requirements regarding fall protection and the shut-off device of the pressurized gas bottle. All further functionalities of the extraction fitting are integrated in at least one additional module, which is connected to the base module in a fixed but removable manner and without impairing the fall safety.

Abstract: A gas supply pipeline system having at least two outlets which are designed in each case for different pressures, for example for 300 bar and for 200 bar. For this purpose, at least one of the outlets is equipped with a valve for pressure reduction. In this way, the extraction of gas at different extraction pressures is possible with one arrangement.
