DIRECT CONTROL VARIABLE DISPLACEMENT METERING PUMPS

A system includes a variable displacement pump (VDP (102)) in fluid communication with an inlet line (104) and with an outlet line (106). The VDP (102) includes a variable displacement mechanism (108) configured to vary pressure to the outlet line (106). An electromechanical actuator (EMA (110)) is operatively connected to actuate the variable displacement mechanism (108). A flow sensing valve (FSV (112)) connected in the outlet line (106). The FSV (112) includes a sensor configured to generate sensor data indicative of flow out of the outlet line (106). A controller (118) is operatively connected to the EMA (110) to control the variable displacement mechanism (108) based on the sensor data to support flow demands from one or more downstream systems.
