Abstract
A method and a system for controlling a separator unit for multiphase separation of fluids of different densities, wherein either a pressure in the separator unit or a level of one or more of the liquids in the separator unit is adjusted in relation to a reference value. The reference value and the relevant pressure in the separator unit (1), or the level of the relevant liquid converted to a pressure, are supplied to either side of a pressure sensitive mechanical device (23; 28) which moves with deviations of the pressure from the reference value, and the movement is transferred directly to a mechanical control unit (22; 33) which is coupled to a control device (20; 38) on a fluid outlet (25; 37) from the separator unit (1), and which utilizes the difference between the pressure in the separator unit and the pressure downstream of the control device for moving this in the desired direction for correcting for the deviation.
