Gas container equipped with such a valve unit.

A cryogenic fluid purification device comprising: a first container defining an interior region; a second container defining an interior region in fluid communication with the interior region of the first container; and a cryogenic fluid in contact with an exterior of the second container.

A device that can be attached to the outlet of a gas cylinder, which can monitor and display in digital or analog form the pressure of the gas in the cylinder and the interval of time remaining until the amount of gas in the cylinder will reach a predetermined lower threshold at a given flow.

A method for controlling a monitoring unit for the residual supply time for the gas present in a pressurized container includes associating with a plurality of angular positions respective residual time values in accordance with a selected flow; measuring the angular position of the control element by means of a magnetic tunnel effect angle sensor. A residual time value is determined in accordance with the selected flow corresponding to the angular position of the rotary control element; measuring an intensity of the magnetic field by means of the magnetic tunnel effect angle sensor TMR. A limit intensity value is defined for the magnetic field. A display device displays the residual time value in accordance with the selected flow only if the intensity of the magnetic field measured is less than the limit value.
