The present invention provides an electromagnetic flow meter (50), a spraying system, and an unmanned aerial vehicle, the electromagnetic flow meter (50) comprising: a main body (10) having an inlet and an outlet; the at least two flow tubes (20) are arranged in the main body (20), each flow tube (20) is communicated with the outside through an inlet and an outlet, and each flow tube (20) is provided with a pair of detection electrodes (21); and the at least one electromagnet (30) is arranged in the main body (10), and one side of each flow pipe (20) is adjacent to one electromagnet (30) in the at least one electromagnet (30). According to the spraying system, the spraying uniformity of the left side and the right side of the machine body during spraying operation can be improved, meanwhile, one-by-one flow calibration operation on a plurality of pumps (70) is avoided, and the spraying operation time is shortened.

    一种电磁流量计(50)、喷洒系统及无人机,其中,电磁流量计(50)包括:主体(10),具有入口及出口;至少两个流量管(20),至少两个流量管(20)设置在主体(20)内,且每个流量管(20)均通过入口及出口与外部连通,每个流量管(20)上均设有成对的检测电极(21);至少一个电磁铁(30),至少一个电磁铁(30)设置在主体(10)内,且每个流量管(20)的一侧均相邻至少一个电磁铁(30)中的一个电磁铁(30)。该喷洒系统可提高喷洒作业时,机身左右两侧的喷洒均匀性,同时避免对多个泵机(70)进行一一流量校准操作,减少喷洒作业时间。
