description 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. L'invention porte d'une manière générale sur des dispositifs et des méthodes modulant le débit de liquides en utilisant la pression, et sur l'application modulée de pression aux flux liquides pour en réguler la pression et le débit, indépendamment de l'emplacement des liquides par rapport aux divers dispositifs. Par exemple, dans une série de dispositifs, connectés chacun à un autre par un conduit, on peut placer des unités de modulation de pression entre les dispositifs pour élever ou abaisser la pression et/ou le débit du liquide passant d'un dispositif au suivant. On peut ainsi régler individuellement la pression et le débit du liquide d'apport alimentant chacun des dispositifs interconnectés.
