ABSTRACT:
An automatic oil well control and monitoring system is disclosed which controls energization of a motor for an oil well pump jack. A first timer intermittently energizes the pump motor so that fluid flows from the well. A total pumping time clock is energized, as is an oil pumping time clock. If the pump begins to pump water, then a probe senses the water rather than oil, and this causes cessation of the oil pumping time clock energization and de-energization of a green indicator lamp. Upon pump-off of the well, a switch sensing fluid flow from the well is opened and the pump motor is de-energized. If no fluid is produced from the well after a time period following initial motor energization, a second timer is actuated to indicate a malfunction condition and a red light is illuminated. Also, the control circuit is continuously energized to maintain a lockout of the pump motor starter. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
