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 8):
The gas control system according to  claim 6 , wherein\n the second control is PID control, and in the PID control as the second control, the control part sets a proportional gain to a larger value in the second state than in the first state.
