Abstract: Embodiments of a flow system are provided. The flow system includes a flow source device configured to receive fluid from a first flow line and output fluid on a second flow line. An output is in fluid communication with the flow source device on the second flow line. An actuation system is in fluid communication with the second flow line through a third flow line. A flow meter measures a flow rate in the second flow line without bypassing any fluid to the first flow line. A controller is in communication with the flow source device and the flow meter. The controller adjusts the flow source device to achieve a desired flow rate at the output based on a condition of the flow source device and the flow rate measured by the flow meter.
