13. A method for controlling production of a production fluid in a well, comprising:
directing a flow of the production fluid through a housing into a production conduit;
directing at least a portion of the flow of the production fluid through a rotor chamber disposed in a subterranean portion of the well to rotate a rotor disposed in the rotor chamber;
detecting a transition in a fluid composition of the production fluid based on a variation in a rotational speed of the rotor;
identifying a phase change using a threshold percentage change in revolutions per minute (RPM) within a threshold time interval, wherein the threshold percentage change is greater than or equal to 10% and the threshold time interval is less than or equal to 5 minutes; and
adjusting the flow of the production fluid in response to the detected transition.
