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.
