ABSTRACT:
An apparatus for generating an oxygen enhanced gas by removing nitrogen gas from air, includes a compressor, absorption columns for removing the nitrogen gas from the pressurized air supplied from the compressor, a flow rate measuring device provided downstream of the absorption columns, a manner of measuring ultrasonic oxygen concentration that includes a manner of generating a correction coefficient for a ratio between oxygen and argon gases contained in the oxygen enhanced gas based on the flow rate of the oxygen enhanced gas measured.
