Abstract:
Mass flow control systems and methods for controlling the mass flow rate of a gas through a primary conduit are disclosed. One mass flow control system includes a primary conduit for directing a flow of a gas and an adjustment system configured to divert a portion of the gas from the primary conduit to a secondary conduit and provide an adjustment signal that changes when a composition of the gas changes. A mass flow controller is operatively coupled to the primary conduit to control a primary flow rate of the gas. The mass flow controller includes a valve to control the primary flow rate of the gas and a control loop configured to receive the adjustment signal and control the valve to provide the primary flow rate of the gas at a set point.

Claim (Index 6):
The mass flow control system of  claim 5 , wherein the pressurization system includes:\n an upstream valve and a downstream valve disposed within the secondary conduit, wherein the thermal mass flow sensor of the means for providing the second measure of the assessment flow rate and the rate of change meter are disposed between the upstream valve and the downstream valve; wherein the pressurization system includes an assessment-flow controller configured to:\n open the upstream valve to divert the portion of the gas from the primary conduit to the secondary conduit and close the downstream valve to pressurize the gas; \n close the upstream valve while the downstream valve is closed to trap the pressurized gas in a portion of the secondary conduit that includes the known volume; and \n open the downstream valve while the upstream valve is closed to produce the assessment-flow that has the changing pressure.
