Water treatment systems are evolving rapidly, driven by the need for greater efficiency, sustainability, and real-time monitoring. One of the most critical components in this transformation is accurate flow measurement. Traditional methods are being replaced or enhanced by smart technologies that leverage the Industrial Internet of Things (IIoT) and Artificial Intelligence (AI). These innovations are not only improving data accuracy but also enabling predictive maintenance, remote monitoring, and automated control in water treatment plants . Modern flow meters now come equipped with embedded sensors and wireless communication modules. This allows them to send real-time data to centralized platforms where AI algorithms analyze trends and detect anomalies. For example, a sudden drop in flow rate could indicate a blockage or leak, and AI can alert operators before serious damage occurs. This level of intelligence is transforming how utilities manage water distribution and treatment proc...
