A compressed gas regulator with integral flow meter is disclosed. The regulator includes pressure reducing section and a flow control section, as well as, a Bourdon tube gauge disposed within the protective surround of the regulator body to prevent physical damage to the gauge. The Bourdon tube is mounted on a gauge adapter that provides for rotation of the tube within the regulator body, yet maintaining a gas seal with the high pressure gas supply. The gauge adapter provides a means for fluidly communicating the high pressure level to the Bourdon tube, yet allowing rotation of the Bourdon tube for zeroing and calibration purposes. An indicator ring, also disposed within the regulator body, is mounted on the Bourdon tube so that the pressure level is readily ascertained by viewing the indicator ring through an aperture in the regulator body. An improved flow meter or flow control device is also disclosed that includes a filter and coined flow aperture plate that is economical to manufacture yet provides improved functionality in filtering particulates from the gas emerging from the flow meter.
