Abstract:
A liquid level meter (100) and an unmanned aerial vehicle. The liquid level meter (100) comprises a first support (110), a main body (120), an elastic member (130) and a sensor module (140), wherein the lower end of the first support (110) is used for being connected to a fixing structure (211); the main body (120) is movably connected to the upper end of the first support (110); the elastic member (130) is arranged between the main body (120) and the first support (110) and is used for providing the main body (120) with an upward pre-tightening force; and the sensor module (140) is arranged on the main body (120) and is used for sensing a magnetic flux. When the liquid level meter (100) can be arranged on a part such as the fixing structure (211) of an unmanned aerial vehicle frame (210), it is guaranteed that the liquid level meter (100) is tightly attached to the bottom of a container (220) located thereabove by using the pre-tightening force provided by the elastic member (130), such that the reliability and accuracy of the liquid level meter (100) are improved.
