Abstract
An apparatus for controlling and monitoring an electrical motor used to pump petroleum from beneath the surface of the earth. A computerized metering apparatus is used to monitor overload power, underload power, as well as other conditions. When the demand power consumption of the electric motor exceeds or falls below preprogrammed limits, the computer provides an indication of the detected condition. A display panel with a particular combination of display lights is thus controlled by the computer to provide oil well service personnel with an indication of a detected problem, even from a distance. This allows service personnel to monitor the condition of a well without getting out of their service vehicle. Additionally, capability is provided to respond to signals provided from the company supplying electric power in order to control the pumping unit.
