The optic-fiber sensor for measuring steam quality has been made out based on the principle of refractivity modulation. It is made up of optic head, conduct optic fiber, light source, detector and electric circuits. Reflectivity on the boundary between optic head and two-phase steam flow can be determined by refractivity of both sides of the boundary. Intensity of reflected light on the boundary is related to the ratio of water and steam. Provided we know the value of temperature or pressure of the two-phase flow, densities of water and vapor can be known and steam quality can be converted from the volume ratio of water and steam. The measuring range of steam quality is 0-100%, and the accuracy is decided by the level of steam quality measured and by resolution power of the sensor. The resolution and sensitivity of the sensor can be tested with two sorts of liquid of known refractive index. Meanwhile, the stability of output of the sensor is also approved. The sensor has been successfully used in measurement of steam quality in a steam-injection oil well with temperature of 270°C and pressure of 8MPa. The measuring result of steam quality tallies with the actual situation.
