Methods and apparatus for use in a welibore to meter and choke certain components from being produced, based upon their density relative to the density of oil are described herein. The device includes an inner tubular body portion having apertures in the wall thereof for passing oil, an outer tubular body and at least one metering orifice therebetween to meter production. Disposed around the inner body is an axially movable member to selectively cover and expose the apertures of the inner body, thereby permitting fluid to flow therethrough.
