Steam flow meter is usually applied to a saturated or a superheated steam flow to secure the reliability and the accuracy of the indicated value. However, it is sometimes used to a wet steam flow piping in actual field because of the heat loss of the piping. This report summarizes the characteristics of various steam flow meters in the wet steam flow based on previous researches. The indicated value of orifice, vortex and ultrasonic flow meter in the wet steam were experimentally investigated. As a result, even their measurement principals are different, they all have the tendencies that the indicated value becomes smaller than the actual flow rate when the steam wetness increases. And also, the correction method of indicated value for each flow meter were suggested to evaluate the actual flow rate.
