RPC Rod Pump Controller

The Unico RPC Rod Pump Controller provides economical pump-off control of sucker-rod pumping systems. Using sophisticated modeling and control software and a powerful digital signal processor (DSP), the RPC controller computes surface and downhole conditions to best regulate the starting and stopping of the pump via a separate motor controller. Comprehensive monitoring and reporting capabilities provide real-time surface and downhole dynamometer plots, daily gauging, fault and event logging, a user-configurable data sampler, and more. Wireless, radio, cellular, and satellite options allow monitoring at any distance. With optional GMC® Webbased telemetry software, users can monitor multiple fields simultaneously from virtually anywhere in the world. RPC units are rugged and have been designed to withstand the harsh environments of the oil patch.
