Zusammenfassung:	It is provided a fluid flow control device 100 for establishing a controllable fluid communication between an external fluid reservoir 120-122 and a base pipe 102 constituting part of a production string 101, as well as a production string 101 and a method using such a fluid flow control device 100. The fluid flow control device 100 comprises a primary flow path 2 arranged inside a fluid control device housing 8, a secondary flow path 7 and a movable valve element 9 arranged at and/or within the primary flow path 2. A major portion of the length of the secondary flow path 7 extends outside the fluid control device housing 8.
