Abstract: The disclosed embodiments include a method for improving a mass flow controller.

Abstract: A mass flow controller includes a fluid inlet, a fluid outlet, and a conduit defining a flow path along which the fluid flows through the mass flow controller. The mass flow controller includes an inlet block having an inlet aperture, an inlet channel fluidly coupled to the conduit, and one or more restrictors positioned along the flow path between the inlet aperture and inlet channel to minimize flow perturbations when a rate of decay measurement is taken or when flow the amount of pressure supplied to the valve inlet is otherwise interrupted.

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.
