Abstract

A method to control a flow rate in a fluid flow network is disclosed. The method includes setting the outlet port of an upstream pressure regulator in a flow control device to have a first constant pressure that is below a minimum upstream pressure delivered from a upstream portion to the inlet port of the upstream pressure regulator, setting the outlet port of a downstream pressure regulator in the flow control device to have a second constant pressure to maintain a constant pressure differential across the downstream pressure regulator, and maintaining, based on the minimum upstream pressure to the flow control device exceeding the first constant pressure and further based on the constant pressure differential maintained across the downstream pressure regulator, the flow rate of the flow control device at a constant value.
