Specifically, by using energy recovery components and secondary batteries 205, the smart water meter of the present application does not need external AC power or regular battery replacement, thereby solving the problem that traditional smart water meters require external power supplies. The above-mentioned hydrodynamic turbine 107 combined with the energy recovery component can use the kinetic energy of the water flow to charge the secondary battery, ensuring the long-term stable operation of the smart water meter, while also reducing electricity costs and the trouble of replacing batteries; by using the Internet of Things main control board 106 and antenna 203, the smart water meter can be connected to the remote management system, and relevant information can be displayed through the display screen 204, remote monitoring, remote meter reading and fault diagnosis can be achieved, the intelligence level of the smart water meter is improved, and it helps to optimize water supply management and maintenance efficiency.
