Abstract: An apparatus for controlling the flow of a gas, containing a controllable valve, wherein the position of the valve and the gas pressure upstream of the valve are measured and used in conjunction with a first lookup table to determine the flow rate of the gas through the valve; and a flow restrictor upstream of the controllable valve, wherein the temperature of the flow restrictor and the gas pressure upstream and downstream of the flow restrictor are measured and used in conjunction with a second lookup table to determine the flow rate of the gas through the flow restrictor.

Abstract: A method and apparatus for self-calibrating control of gas flow. The gas flow rate is initially set by controlling, to a high degree of precision, the amount of opening of a flow restriction, where the design of the apparatus containing the flow restriction lends itself to achieving high precision. The gas flow rate is then measured by a pressure rate-of-drop upstream of the flow restriction, and the amount of flow restriction opening is adjusted, if need be, to obtain exactly the desired flow.

IPC: G05D7/06
Abstract: A method and apparatus for the controlled splitting of a fluid flow into multiple channels, where an input command specifies the flow in each channel as a percentage of the total flow. The flow in each channel is controlled by a valve capable of moving to a specified position, where the position is determined as a function of the specified percentage, the pressure upstream of the valve, and the pressure downstream of the valve.
