る。 As is well known, in a process of mixing two fluids, it is important to accurately measure the mixing ratio. In particular, when two fluids are mixed as a pre-stage of a specific reaction, it is essential to control the mixing ratio to a constant level in order to ensure a smooth reaction. In such cases, it is impossible to accurately measure or calculate the mixing ratio.

測する既存の手段は、以下に示す通りである。 Conventionally, a mechanism for mixing a certain amount of water vapor into gas is as shown in FIG. 1, for example. 1 in the diagram
is a humidifier. This humidifier 1 is connected to a supply gas conduit 2 for introducing gas and a water conduit 4 for introducing water and having a water flow meter 3 interposed therebetween.
The water in the humidifier 1 is heated to steam, mixes with the gas supplied from the supply gas conduit 2 to form a mixed gas, and is sent out through the mixed gas conduit 5. This mixed gas conduit 5 is provided with a mixed gas analyzer 6 and a mixed gas flow meter 7 in this order. Existing means for measuring the mixing ratio of mixed gas using such a mechanism are as shown below.

であること等の欠点がある。(1) A method of directly measuring moisture in a mixed gas using a mixed gas analyzer 6. However, according to these methods, firstly, the mixed gas analyzer 6 is expensive, secondly, the delay of the mixed gas analyzer 6 itself is large and may significantly impair controllability, and thirdly, the problem is that the mixed gas analyzer 6 is expensive, There are drawbacks such as difficulty in measuring close moisture content.

However, this method has the disadvantage that it can only be used when no water is accumulated in the humidifier 1, that is, when the liquid level is always constant.

方法を満足できない。(3) A method of measuring the flow rate of the mixed gas with a mixed gas flowmeter 7 and predicting the amount of water vapor in the mixed gas.
However, this method has the disadvantage that the mixing ratio of water vapor must be assumed. Regarding (3) above, as a method for predicting the mixing ratio of water vapor in the air,
29357 is known. This method measures the air temperature, assumes that the air is saturated with water vapor, and assumes that the amount of water vapor in the air is equal to the saturated amount of vapor. However, according to this method, it is certainly possible to predict the above mixing ratio if the water vapor in the gas mixture is always saturated, but it is difficult to create a completely saturated state industrially, and The amount of water vapor in the water vapor body is always below the saturated vapor amount. Therefore, it cannot be said that the amount of water vapor in the air is accurately predicted, and method (3) above cannot be satisfied.

Then, Q 2 = Q 1 + Q 3 ...(3) Mw 2 = Q 1 /Q 1 +Q 3 Mw 1 +Q 3 /Q 1 +Q 3 Mw 3 ...(4) holds true. Substituting equations (3) and (4) into equation (2), ΔP 2 = α 2 (Q 1 + Q 3 ) (Q 1 AMw 1 A + Q 3 Mw 3 )
