The present invention generally relates to devices and methods for affecting the flow rate of fluid using pressure. The invention generally provides for controlled application of pressure to flowing fluids to control pressure and flow rates of those fluids, independent of location of the fluids relative to various devices. For example, in a series of devices, each connected to another via a conduit, pressure control units can be provided between devices to raise or lower pressure and/or flow rate of fluid flowing from one device to the next. In this way, a series of interconnected devices can be arranged such that inlet fluid pressure or flow rate of any individual device can be set independently of every other device.
