A flow control apparatus includes a housing having a bore extending and a port formed through a wall of the housing; and a port sleeve disposed in the housing and having a port in communication with the port of the housing. The apparatus also includes a first sleeve releasably attached to the housing, wherein the first sleeve is movable from a first position preventing axial movement of the port sleeve relative to the housing to a second position allowing axial movement of the port sleeve relative to the housing. The apparatus further includes a second sleeve releasably attached to the port sleeve, wherein the second sleeve is movable from a first position blocking fluid communication through the port of housing and the port of the port sleeve to a second position allowing fluid communication through the ports.
