Disclosed is a pilot pressure system, comprising a flow path comprising a first inlet and a first outlet, wherein the flow path is configured to create a specific pressure drop between the first inlet and first outlet based upon one or more characteristics of a fluid flowing within the flow path. The pilot pressure system further comprises a pilot pressure line, the pilot pressure line comprising a second inlet and a second outlet, wherein the second inlet is configured to allow the pilot control line to be in pressure communication with the flow path, and the second outlet of the pilot control line is configured to be connected to a sealed pilot pressure chamber of a downhole flow control device.
