ABSTRACT:
An assembly for handling a fluid, comprising a valve and a controller. The valve has at least one revolving valve element and a coupling device. The coupling device comprises at least one port coupled to a flow path and is adapted for interacting with said at least one revolving valve element in order to control a fluid flow through said at least one port using a relative valve position between the revolving valve element and the coupling device. The controller is adapted for controlling the relative valve position based on at least one of a current and a previous measurement of an amount of the fluid flow dependent on the relative valve position.
