The cart can include a transmitter configured to transmit a signal indicative of the weight applied to the load cell. The system can include a receiver configured to receive the signal from the transmitter. The system can include a computing system in communication with the receiver. The computing system can include software configured to correlate the signal indicative of the weight of the cryogenic fluid tank to a fill amount of the tank.

Systems and methods are provided for a combined defuel and priority panel for a fueling station. The defuel and priority panel is configured to defuel a compressed natural gas (CNG) vehicle and direct the defueled gas to fuel other CNG vehicles at the panel fueling and defueling site. The defuel and priority panel is also configured to store defueled gas in defuel storage tanks, which can then be used to later fuel CNG vehicles.

The present invention provides a control system (10) for managing the supply of bottled gas to users (12), the system comprising: a gas cylinder system (14) having a gas cylinder (15) for receiving and distributing gas contained therein; a first electronic monitoring system (16) associated with said gas cylinder system (14) and operable to monitor parameters associated with said cylinder system (14); a second monitoring system (18) associated with one or more locations (A-F) in which said cylinder may reside and being operable to monitor the presence or absence of said cylinder within said one or more locations (A-F); and a computer system (20) in communication with each of said second monitors (18) for receiving information therefrom relating to the presence or absence of said cylinder system (14) in said one or more locations (A-F).

The disclosure relates to a storage device for storing gas and supplying a consumer with different gas pressure levels, comprising at least one low-pressure storage tank and at least one high-pressure storage tank. According to the disclosure, the low-pressure storage tank is connected to a low-pressure connection via a switchable first valve and the high-pressure storage tank is connected to a high-pressure connection via a switchable second valve, wherein it is possible to provide a connected consumer with a higher gas pressure level via the high-pressure connection than via the low-pressure connection. The low-pressure connection and the high-pressure connection are connected to each other via a switchable third valve. Furthermore, the tanks are connected to each other via a fourth valve. The valves are switchable in such a way that the low-pressure storage tank can be emptied to a lower minimum pressure level than the high-pressure storage tank.

A fluid supply warning and communication system including fluid tight engagements being made with tubing having at least one connector end chosen from a universal connector, a twist-on nipple, and a v-shaped end. A gas supply warning and communication system including a first upstream gas path, a second upstream gas path, and a downstream gas path made with tubing having at least one connector end chosen from a universal connector, a twist-on nipple, and a v-shaped end. A method of increasing humidity in a downstream gas path in the gas supply warning and communication system by flowing gas through a downstream gas path tubing that increases humidity to an end use appliance.

A system for dispensing cryogenic liquid to a use point includes a bulk tank containing a supply of carbon dioxide or other cryogenic liquid and a pressure builder that is in communication with the tank via a pressure building valve. The pressure builder uses heat exchangers to vaporize a portion of the cryogenic liquid as needed to pressurize the bulk tank. The pressurized cryogenic liquid is dispensed through a dispensing line running from the bottom of the tank. A vent valve also vents vapor from the tank to control pressure. Operation of the vent and pressure building valves is automated by a controller that receives data from sensors. The controller determines the required saturation pressure for the tank and varies the tank pressure to match and provide a generally constant outlet pressure depending on conditions of the cryogenic liquid.

Fluid tanks in a hospital or similar environment include sensors to detect, e.g., state and location, which can be communicated to a central station where this data can be processed to permit predictions of resource usage and enable automated management of the fluid tanks.

A pressure vessel system has a pressure vessel for storing gaseous fuel, a fuel line, and a total-pressure sensor for measuring a total pressure of the fuel at a position within the fuel line. This makes it possible for various functions, such as the control of power reduction, for example, to be performed more accurately than if only static pressure were being used. The technology disclosed here also relates to an energy supply arrangement having such a pressure vessel system and having an energy converter, such as a fuel cell, for example.

The invention relates to a device for providing pressurized fluid. The device includes a first functional assembly including a pressurized fluid bottle having an opening having attached therein a first tap including an inner fluid circuit including an insulating valve. The device includes a second functional assembly forming a physical entity separate from the first assembly. The second assembly includes a second tap having an inner fluid circuit. The first tap and the second tap include respective coupling members forming a removable rapid connection system. The device includes in the first assembly at least one electronic data storage communication unit that is removably, wirelessly queryable via electromagnetic waves and in that the second assembly includes at least one electronic communication unit for removably, wirelessly reading, via electromagnetic waves, data from the electronic member of the first assembly.

A medical gas alarm systems and associated methods are disclosed. A method of monitoring the medical gas system includes the steps of monitoring a characteristic of a medical gas system using at least one monitoring instrument positioned in a medical gas supply network; generating and sending a particular signal from the monitoring instrument to a CPU when the characteristic measured by the monitoring instrument passes a predetermined threshold; generating a fault signal from the CPU when the CPU determines that a fault condition has occurred; retrieving a stored message from the CPU in response to the fault signal, and in which the stored message other than the fault or threshold condition monitored by the instrument; and sending the stored message from the CPU to an output at a medical gas alarm module.
