Claims

[Scope of utility model registration request]

(1) A first flow path flowing through at least each of the first and second channels.
and a fluid mixing control device for mixing and supplying a second fluid at a predetermined ratio, the device comprising: a means for detecting a flow rate of a first fluid flowing through the first flow path; and a means for detecting a flow rate of a first fluid flowing through the first flow path; A first step that controls the first fluid flow rate in the first flow path so that the deviation between the flow rate and the first set value becomes zero. controller,
Detecting means for detecting a second fluid flow rate flowing through the second flow path;
a second controller that controls the second fluid flow rate in the second flow path so that the deviation between the detected second fluid flow rate and the second set value becomes zero; and the first controller The first setting value of is inputted to the ratio setting device that sets the ratio at the predetermined rate, with or without a delay element, and the output of the ratio setting device is inputted to the second setting value of the second controller. A fluid mixing control device comprising: means for supplying a set value.

(2) Utility Model Registration The fluid mixing control device according to claim 1, wherein the delay element is a first-order delay element.
