Disclosed is a liquid level meter, comprising a measurement assembly (10) and a detection device (20). The measurement assembly (10) comprises a first measured unit (11), a second measured unit (12) and a connecting piece (13), wherein the connecting piece (13) is configured to flexibly connect the first measured unit (11) and the second measured unit (12); and after the first measured unit (11) rises to a first height in a liquid, the first measured unit (11) can drive the second measured unit (12) to float by means of the connecting piece (13). The detection device (20) can detect the position of at least one of the first measured unit (11) and the second measured unit (12), and generate a liquid level measurement signal on the basis of detected position information. In the liquid level meter, the second measured unit and the first measured unit are arranged in linkage manner, such that when the first measured unit exceeds a measurement range, the second measured unit can be detected, thereby increasing the total range of the liquid level meter. Further disclosed are a spraying assembly provided with the liquid level meter, and an unmanned aerial vehicle.

    一种液位计,包括测量组件(10)以及检测装置(20),测量组件(10)包括第一被测单元(11)、第二被测单元(12)以及连接件(13);连接件(13)被配置成柔性连接第一被测单元(11)以及第二被测单元(12),第一被测单元(11)在液体中上升到第一高度后,第一被测单元(11)能够通过连接件(13)带动第二被测单元(12)上浮;检测装置(20)能够检测第一被测单元(11)和第二被测单元(12)中至少一个的位置,基于检测到的位置信息生成液位测量信号。该液位计通过联动设置的第二被测单元与第一被测单元,在第一被测单元超出检测量程,第二被测单元能够被检测到,增加了液位计的总量程。还包括一种配置有该液位计的喷洒组件和一种无人飞行器。
