1. A gas pressure regulator comprising:

  • a regulator portion adapted to connect to a source of pressurized gas at a first end and to deliver the gas at a predetermined pressure at a second end; and

    a flow meter having means for selectively varying the rate of flow of the delivered gas, the flow meter having an inlet end, an outlet end opposite the inlet end, and a peripheral sidewall extending between the ends, the flow meter having a longitudinal axis, each end having an end surface, the flow meter secured at the inlet end to the second end of the regulator portion, the flow meter having portions defining a passage through which the gas is delivered for use extending between the inlet end and the outlet end,wherein the means for selectively varying the flow rate comprises a cap rotatably mounted to the end surface of the outlet end, the cap having a hole extending through the cap; and

    wherein the passage through which the gas is delivered extends through the hole in the cap, the passage terminating in an orifice located on the end surface of the outlet end, not at the peripheral sidewall, thereby reducing the length of the flow meter.
