摘要： There is provided a method of, and apparatus for, measuring the mass of a gas under pressure using a piezoelectric oscillator. The gas is contained within a pressure vessel (100) having a fixed internal volume (V) and the piezoelectric oscillator (202) is immersed in the gas within the pressure vessel (100). The method comprises: a) utilizing said piezoelectric oscillator (202) to measure the density of the gas within the high-pressure vessel (100); b) determining, from the density measurement and from the internal volume (V) of said pressure vessel, the mass of the gas within the pressure vessel (100). By providing such a method, the true contents (i.e. mass) of fluid in a pressure vessel such as a cylinder can be measured directly without the need to compensate for factors such as temperature or compressibility. This allows a determination of mass through direct derivation from the density of the gas in the cylinder, reducing the need for additional sensors or complex calculations to be performed.

摘要： The concentration of xenon, in a medical gas mixture of xenon as an active component with a known composition of oxygen and, optionally, nitrogen and/or helium recirculating through a medical device (103) in which carbon dioxide is introduced into the mixture, is monitored by removal (135, 133) of carbon dioxide downstream of the medical device (103) and subsequently passing the carbon dioxide-free gas through an ultrasonic gas analyser (143) upstream of the medical device. The gas analyzer determines the xenon concentration by measuring the time delay between transmission of an ultrahigh frequency ultrasonic pulse of at least 100 kHz axially through the sample chamber from a location at one end thereof and reflection of said pulse axially from the other end of the sample chamber back to said location. An analyser of novel construction is disclosed.

摘要： A gas storage container may be filled with gas under pressure by feeding cryogenic fluid comprising liquefied gas into the container through a first conduit arrangement in a nozzle inserted into a passageway through a fluid flow control unit mounted in an opening in said container; closing the container to the passage of gas into or out of said container; and allowing said cryogenic fluid to become gaseous within the closed container. The invention involves venting displaced air and/or gaseous cryogenic fluid from said container during the feeding step through a second conduit arrangement in the nozzle. In embodiments in which displaced air and/or gaseous cryogenic fluid flows through the second conduit arrangement around a length of the first conduit arrangement, heat transfer from the fluid flow control unit to said cryogenic fluid is suppressed thereby reducing the level of evaporation of the cryogenic fluid in the nozzle during fill.
