ABSTRACT:
A closed feedback control system for injecting radioactive material into a high pressure well stimulation fluid line is provided which allows the injection rate to be controlled based upon desired and actual values. A controller calculates a desired injection rate based upon job characteristics, compares the desired rate, and then uses a PID algorithm to control the injection rate until the actual and desired rates are equal. Additionally, the injection system is controllable by a manual control device affixed to the previously mentioned controller, or by utilizing a separate manual control unit.
