Abstract: The present invention relates to a method of improving flow stability for a multiphase fluid flowing through a tubular element (1), comprising arranging a flow control device (2) along a flow path (F) through the tubular element (1), the flow control device (2) comprising a housing (4), an inlet (10) arranged on an upstream side of the control device (2), an outlet (23, 13) arranged on a downstream side of the control device (2), and a movable body (9) provided within the housing (4) along an internal flow path (11) through the control device (2) from the inlet (10) to the outlet (23, 13), the body (9) being arranged such that changes in velocity and/or properties and/or composition of the fluid flowing along the internal flow path (11) result in changes to the forces acting on the body (9) as a result of the Bernoulli principle, thereby adjusting the flow of fluid through the control device (2).
