ABSTRACT:
An integral gas regulator and flowmeter unit. The unit has a housing body with a high pressure gas inlet, a low pressure gas outlet, and a receptacle. A passage communicates gas to a valve seat in the receptacle. A differential pressure piston having seals at each end is slidably received within the receptacle and is spring biased away from the valve seat. A first end of the piston cooperates with the valve seat for controlling gas flow into the receptacle. A bore within the piston communicates gas from the first end to a second end of the piston. A floating inner flow tube mounted on the second end of the piston receives gas from the bore. A ball is slidably received within the inner flow tube. An outer flow tube overlies the inner flow tube. Both tubes are arranged for being positioned in a normally vertical position and may be marked with graduations for indicating the ball position. Thus, the pressure of a gas is reduced from a high pressure to a desired lower pressure, and the flow rate of the gas is indicated. A low pressure gas passage communicates low pressure gas from the flowmeter to the outlet. A flow adjusting valve may be provided. A pressure gauge may also be included to indicate the pressure of the gas entering the unit.
