An apparatus ( 10 ) is provided for determining the flow rate of a gas. The apparatus comprises a housing ( 12 ) forming a vaporization chamber ( 14 ) for converting a fluid into a gas vapor when subjected to heat ( 22 ). An oscillation flow meter is formed within the housing ( 12 ), thereby being integrated with the vaporization chamber, for receiving the gas vapor and providing a frequency signal ( 60 ) indicative of the rate of flow of the gas vapor.
