Abstract:
The present invention makes it easy to control the amount of material gas led out of a tank. Accordingly, carrier gas is introduced into a tank containing a material and together with the carrier gas, from the tank, material gas produced by vaporization of the material is led out. A control part controls the flow rate of the carrier gas so that a concentration index value obtained by measuring mixed gas led out of the tank and indicating the concentration of the material gas in the mixed gas comes close to a predetermined target concentration index value. In addition, the control part controls the flow rate of the carrier gas to change at a predetermined change rate, and then controls the flow rate of the carrier gas on the basis of the deviation between the concentration index value and the target concentration index value.

Claim (Index 13):
A gas control system adapted to introduce carrier gas into a tank containing a material, and by together with the carrier gas, from the tank, leading out material gas produced by vaporization of the material, intermittently lead out a predetermined amount of the material gas from the tank, the gas control system comprising:\n a control part that performs PID control of a flow rate of the carrier gas so that a concentration index value obtained by measuring mixed gas led out of the tank and directly or indirectly indicating concentration of the material gas in the mixed gas comes close to a predetermined target concentration index value; and a calibration data storage part that as calibration data, stores a temporal change in the concentration index value obtained by PID control performed by the control part on the predetermined amount of the material gas led out of the tank for a first time, wherein when performing the PID control of the predetermined amount of the material gas led out of the tank for a second time or thereafter, the control part refers to the calibration data to set a controllable range that defines upper and lower limits of an operation amount of the flow rate of the carrier gas, the flow rate being determined on a basis of a deviation between the concentration index value and the target concentration index value in the PID control.
