PROBLEM TO BE SOLVED: To provide a vapor dryness or wetness measuring device wide in a measurable range of dryness and enable simple measurement of dryness or wetness. SOLUTION: A vapor feed pipe 2 to feed vapor to be measured is connected to a measuring container 5 to store a given amount of liquid. An ultrasonic vapor amount detecting means 20 to detect an amount of vapor to be fed is mounted. Temperature sensors 18 and 19 to detect the temperature of the liquid at an internal part are mounted on the side of the container 5. From the increase of the temperature of liquid in the container 5 and a feed vapor amount, enthalpy of vapor to be measured is computed and from the enthalpy, dryness or wetness of vapor is calculated. |
