摘要：An oxygen concentration apparatus (300) according to the present inventionhas: pressure swing adsorption type oxygen concentration means (310); and a controlmeans (350) that controls switching means (316) that switches between intake of

pressurized air into an adsorption column (312) and exhaust from the adsorption column.The switching means is controlled based on pressure in oxygen concentrated gas in theconduit measured by pressure measuring means to adjust a cycle of adsorption andregeneration processes of the oxygen concentration means so that pressure at theupstream of flow rate adjusting means (340) can be controlled and, as a result, the needfor a mechanical pressure regulating valve, that has been needed conventionally, can beeliminated. Further, there is also shown a gas supply apparatus that comprises ultrasonictype gas concentration and flow rate measuring means that comprises, in turn, twoultrasonic transducers that is disposed in an opposed manner in the conduit throughwhich product gas flows so that a concentration value measured when the product gasoutput is stopped is determined to be a product gas concentration.
