Method and apparatus for real-time detection of the level of the cryogenic liquid in a container. The cryogenic liquid level detection apparatus includes a liquid level indicator, a floating scale, and a buoy attached at a bottom end of the floating scale. A top end of the floating scale moves against calibrated markings of the liquid level indicator, thereby indicating the level of the cryogenic liquid in real-time.

Various embodiments provide an end-to-end gaseous fuel transportation solution without using physical pipelines. A virtual pipeline system and methods thereof may involve transportation of gaseous fuels including compressed natural gas (CNG), liquefied natural gas (LNG), and/or adsorbed natural gas (ANG). An exemplary pipeline system may include a gas supply station, a mother station for treating gaseous fuels from the gas supply station, a mobile transport system for receiving and transporting the gaseous fuels, and user site for unloading the gaseous fuels from the mobile transport system. The unloaded gaseous fuels can be further used or distributed.

A cover and/or decorative cover for an oxygen tank. Covers that encompass or wrap an oxygen tank, oxygen cylinder and/or cart holding or supporting an oxygen tank and/or oxygen cylinder and associated valves, tubing and wiring.

An enhanced operating method and an integrated tube-trailers and stationary ground storage system are provided for implementing enhanced pressure consolidation operations for refueling gaseous fuels. The integrated tube-trailers and stationary ground storage system includes gaseous fuel supply tube-trailers and stationary ground storage including at least one or more stationary pressure vessels. A compressor can be supplied by both the stationary ground storage and the tube-trailers. The stationary ground storage can provide higher pressure to the compressor than the tube-trailers, enabling enhanced compressor throughput during refueling operation, and enhanced utilization of tube-trailers payload.

The present invention pertains to a device for controlling a medical gas flow from a cylinder, wherein the device is configured to be releasably attachable to a gas cylinder and wherein the device is capable of identifying a gas cylinder in order to control the opening and closing of a valve comprised in the valve. Accordingly, the device comprises a valve for controlling a gas flow from a gas cylinder, a gas outlet, which is in fluid communication with said valve and positioned downstream of said valve, and a connecting means configured for receiving and releasably connecting a cylinder for providing a fluid connection between a cylinder and said valve. The device furthermore comprises an identifying means for identifying a cylinder, wherein the valve is in communication with the identifying means and is configured to be openable based on the identification of the cylinder.

A nitric oxide delivery device including a valve assembly, a control module and a gas delivery mechanism is described. An exemplary gas delivery device includes a valve assembly with a valve and circuit including a memory, a processor and a transceiver in communication with the memory. The memory may include gas data such as gas identification, gas expiration and gas concentration. The transceiver on the circuit of the valve assembly may send wireless optical line-of-sight signals to communicate the gas data to a control module. Exemplary gas delivery mechanisms include a ventilator and a breathing circuit. Methods of administering gases containing nitric oxide are also described.

A method for filling a fluid container with a cryogenic fluid, the method including the step of reducing with a container temperature reducer a container temperature of the fluid container prior to adding the cryogenic fluid to the fluid container. The method can include additional steps, including: compressing with a compressor the cryogenic fluid based at least partially on the container temperature, controlling with a controller the extent that the compressor compresses the cryogenic fluid, cooling with a fin pack the cryogenic fluid, filtering with a filter the cryogenic fluid, analyzing with a fluid analyzer a fluid within the cryogenic fluid, monitoring with a water monitor a water content of the cryogenic fluid and/or monitoring with a fluid sensor a fluid property of the cryogenic fluid.

A storage tank for cryogenic liquid includes an outer tank constructed of a rigid material and an inner tank contained within and spaced inwardly from the outer tank. A supply line supplies cryogenic liquid to a plurality of cryogenic freezers. A fill line having a diameter greater than the supply line allows the storage tank to be filled at a greater speed relative to filling through the supply line and allows the storage tank to be filled while supply cryogenic liquid to the cryogenic freezers. A level sensor processes an impedance to calculate a level of the inner tank and a reporting unit displays the level and may report the level to a remote server.

A hydrogen dispensing system includes a hydrogen storage tank for storing hydrogen gas, a turboexpander generator fluidly connected to the hydrogen storage tank, and a dispenser fluidly connected to the turboexpander generator. The turboexpander generator receives a flow of the hydrogen gas from the hydrogen storage tank at an inlet of the turboexpander generator, reduces a pressure and a temperature of the flow of hydrogen gas, and outputs the hydrogen gas to the dispenser.
