The website’s ultrasonic water meters achieve high energy efficiency with a low-power design. Compared to traditional water meters, non-mechanical operation reduces energy loss while in idle states, sleep-mode functionality further minimizes power use, and optimized communication modules (such as MBUS) reduce energy waste. In smart grid applications, remote monitoring diminishes manual meter reading requirements, lowering operational energy expenditure. These meters present a low-carbon water management solution for industries and cities focused on environmental impact.
