n: an acoustic electronic device used to monitor the angle of the flex joint on a floating offshore drilling rig. A small angle should usually be maintained on the flex joint to minimize drill pipe fatigue and wear and damage to the blowout preventers and to maximize the ease with which tools may be run. Also called azimuth angle indicator.
