The invention relates to the technical field of micro-displacement detection, in particular to a passive wading sensor, a detection method and a liquid level measurement system. The passive wading sensor comprises a second optical fiber body, the end part of the second optical fiber body is provided with a reflector, and the reflector wraps the end part of the second optical fiber body; the end part of the second optical fiber body is a reflecting surface and is used for reflecting light; the reflecting body further comprises a protruding body, and the protruding body is arranged on the reflecting body, protrudes towards the outer side and is used for reflecting light. According to the passive wading sensor, the intensity of reflected light is changed by utilizing the change of the external refractive index of the passive wading sensor, that is, the external wading condition can be detected by detecting the intensity of the light. According to the embodiment, the fording sensitivity of the sensor can be great
