The utility model provides a device capable of accurately detecting liquid level, which comprises a plurality of groups of light emitting and receiving devices and a lens on the inner wall of a barrel body, the lens is right-angled and forms an incident mirror surface and a reflecting mirror surface, and a plurality of groups of emitting and receiving detection devices which are arranged at intervals along the axial direction of the barrel body are correspondingly arranged on the outer side of the lens. The detection device comprises an emitter corresponding to the incident mirror surface and a receiver corresponding to the reflecting mirror surface, each receiver judges whether liquid exists in the barrel body or not according to voltage changes generated by the intensity of received light, and whether liquid exists at the position of the corresponding height or not can be detected. According to the high-applicability liquid level detection device provided by the utility model, different heights of liquid in
