A flow meter comprises a shell (1), a measuring tube assembly (2) and a circuit board assembly (3), wherein the measuring tube assembly (2) and the circuit board assembly (3) are assembled in a space defined by the shell (1). The measuring tube assembly (2) comprises a measuring tube (20). The measuring tube (20) comprises an inlet (2021), an outlet (2022) and a channel (2023) communicating the inlet (2021) with the outlet (2022). The passage (2023) allows fluid to pass therethrough. The circuit board assembly (3) comprises a circuit board (30), and a first plugging end (31) and a second plugging end (32) which are fixed to the circuit board (30). The housing (1) comprises a first through hole (110) and a second through hole (120). The first through hole (110) is used for exposing the first plugging end (31), and the second through hole (120) is used for exposing the second plugging end (32). The first plugging end (31) is used for being connected with the second plugging end (32) of a second flow meter in a plugging mode so as to achieve the electrical connection between a plurality of flow meters. The proper number of flow meters can be assembled according to the number of water outlet channels of the water pump, so that the additional design and manufacturing of the flow meters are not needed, and the cost is saved.

    一种流量计,包括外壳(1)以及组装至外壳(1)围成的空间内的测量管组件(2)与电路板组件(3)。测量管组件(2)包括测量管(20)。测量管(20)包括入口(2021)与出口(2022)以及连通入口(2021)与出口(2022)的通道(2023)。通道(2023)供流体经过。电路板组件(3)包括电路板(30)以及固定至电路板(30)的第一插接端(31)与第二插接端(32)。外壳(1)包括第一穿孔(110)与第二穿孔(120)。第一穿孔(110)供第一插接端(31)外露。第二穿孔(120)供第二插接端(32)外露。第一插接端(31)用于和第二流量计的第二插接端(32)插接,以实现多个流量计之间的电性连接,可根据水泵的出水通道的数量组装合适数量的流量计,无需另外设计制造流量计,节省了成本。
