Permanent Dynamometer PDM | Leutert Vietnam

A Dynamometer measures the operation of a rod pumping system. A dynamometer card shows the position of the polished rod (x-axis) versus the load on the rod string (y-axis). Dynamometer cards are the main tool to determine the status of the rod pumping system.
