The ultrasonic water meter is a high-accuracy electronic flow meter leveraging the ultrasonic time-of-flight principle. It determines flow velocity by measuring the propagation time disparity of ultrasonic waves in the fluid. Contrasting with conventional mechanical water meters, its notable advantages include: absence of moving mechanical components, broad turndown ratio, negligible pressure drop, superior precision, and extended operational life. It is particularly well-suited for intelligent water management systems, industrial metering applications, and district-level leakage monitoring.
High Accuracy: ±1% to ±2% error, better than mechanical meters (±2% to ±5%).
No Moving Parts: Wear-resistant, lifespan >15 years.
Wide Turndown Ratio (100:1 to 400:1): Measures tiny (e.g., drips) and large flows accurately.
Zero Pressure Loss: Straight-through design doesn’t affect pipeline pressure.
Smart Features: Remote reading, leak monitoring, cloud data management.
