PROBLEM TO BE SOLVED: To provide a gas-liquid ratio acquisition system capable of highly accurately acquiring the gas-liquid ratio of gas-liquid two-phase flow, and to provide a bearing device, a rotary machine and a gas-liquid ratio acquisition method.SOLUTION: The gas-liquid ratio acquisition system includes: a measurement unit 11 having a capacitance sensor for detecting capacitance between surfaces of a rotary shaft 50 and bearing pads 3 facing each other making gas-liquid two-phase flow exist therebetween, and a displacement sensor for detecting the distance between the surfaces; and an arithmetic unit 100 having a gas-liquid ratio determination section for, on the basis of the relation between the capacitance and the gas-liquid ratio beforehand obtained for each distance, calculating the gas-liquid ratio of the gas-liquid two-phase flow from detected values of the capacitance and the distance. |
