n: 1. an instrument or assembly of instruments used to measure torque and other force-related properties of rotating or reciprocating machinery. 2. in sucker rod pumping, a device used to indicate a variation in load on the polished rod as the rod string reciprocates. A continuous record of the result of forces acting along the axis of the polished rod is provided on a dynamometer card, from which an analysis is made of the performance of the well pumping equipment.

a recording of the stresses in a rod string of a beam pumping unit.

n: a continuous record made by the dynamometer of the result of forces acting along the axis of the polished rod in sucker rod pumping.
