Patent ID: 6941965

Claim:
A fluid flow control system, comprising: a fluid inlet to receive a flow of process fluid; a pressure transducer to measure a pressure of the process fluid received at the fluid inlet and provide a pressure signal indicative of an amount of the process fluid received at the fluid inlet; a plurality of fluid outlets, the plurality of fluid outlets including a first fluid outlet and at least one second fluid outlet; a first controlled valve operatively coupled to the first fluid outlet, to receive a first control signal that is based upon the pressure signal, and responsive to the first control signal, to provide a first predetermined portion of the flow of process fluid received at the fluid inlet to the first fluid outlet; at least one second controlled valve operatively coupled to the at least one second fluid outlet, to receive at least one second control signal that is based upon the pressure signal, and responsive to the at least one second control signal, to provide a remaining portion of the flow of process fluid received at the fluid inlet to the at least one second fluid outlet; wherein a ratio of the first predetermined portion to the remaining portion is independent of the amount of process fluid received at the fluid inlet.
