<P>PROBLEM TO BE SOLVED: To provide a droplet measuring device in a steam turbine, which can handle droplets scattering in multi-directions, is not broken in a steam flow having fast flow speed, and accurately measure even if the droplets stick into the device several times, and also to provide a droplet measuring method. Ž<P>SOLUTION: The droplet measuring device comprises: an optical fiber probe 12a measuring the diameters and the moving speed of the droplets scattering in the multi-directions in the steam flow in the steam turbine; a metallic cylinder 14 fixing the optical fiber probe at a position separated from a tip end of the optical fiber probe; an electric heater 15 equipped to the metallic cylinder; and a measuring instrument 16 measuring the temperature of the metallic cylinder. The material of the metallic cylinder 14 is a shape memory alloy or bimetal. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
