ABSTRACT:
A fluid flow control system that includes a fluid inlet to receive a flow of process fluid and a plurality of fluid outlets. The plurality of fluid outlets include a first fluid outlet and at least one second fluid outlet. The first fluid outlet provides a first predetermined portion of the flow of process fluid, and the at least one second fluid outlet provides the remaining portion of the flow of process fluid. In one embodiment, the control system includes a pressure transducer, first and second multipliers, and first and second flow controllers. The first multiplier multiplies a pressure signal received from the pressure transducer by a first setpoint to control a first flow controller that provides the first predetermined portion of the flow of process fluid. The second multiplier multiplies the pressure signal by a second setpoint to control a second flow controller that provides the remaining portion.
