FIELD: engines and pumps.
SUBSTANCE: device, such as a pump controller, consists of a signal processor, adapted at least to receive signaling, containing information on the linear control curve of the check point, at least partially, based on the adaptive control curve of a check point, related to the liquid, pumping in a pump system and to determine the control check point, at least partially, based on the received signaling. The signal processor is configured to provide a control signal, containing information for the pump control, based on the determined control check point.
EFFECT: invention provides a reduction in overall energy consumption and operating costs of the pump controllers.
