For smart cities, smart water meters are essential components of modern infrastructure. They enable city planners to gather real-time data on water consumption across neighborhoods. With this data, cities can manage water resources more efficiently and reduce losses due to leaks or theft. These meters help promote sustainable urban living by encouraging residents to conserve water. By connecting to larger IoT-based smart water management systems, smart meters make water supply networks more intelligent and responsive. They are key to building sustainable, tech-driven cities.
