A system for controlling an articulated loading arm which is mounted on a loading station, and for moving an outer end of the arm into a position above the rail of a tanker moored adjacent the loading station. The system includes a sensor for developing a signal proportional to the height of the tanker rail relative to the loading station, and another sensor for developing a signal proportional to the distance between the tanker and the loading station. The rail height signal and the tanker distance signal are coupled to a computer that develops an output signal which causes the outer end of the loading arm to move into a predetermined position above the tanker rail.
