Dynamometer
GEOSTAR-111.D

The dynamometer is designed to test the sucker rod pump and identify possible failures of downhole equipment
Dynamometer GEOSTAR-111 is designed:
– to register surface dynamometer card of down-hole pumping unit operation;
– to control valves operation;
– to estimate well rate, pumping unit efficiency and torque data.
