Overview
The pulse-based water meter is a residential ultrasonic water meter that incorporates cutting-edge technology. It seamlessly integrates intelligent wireless communication, advanced data analysis capabilities, and exceptional metrological performance, resulting in a substantial reduction in non-revenue water and enhanced utility benefits. The pulse water meter boasts an innovative design and offers a design life time of 15 years, surpassing that of conventional mechanical water meters. With its non-moving components, it maintains consistent accuracy and requires zero maintenance throughout its entire operational lifespan. Furthermore, it achieves a maximum allowable pressure (MAP) of 16 bar, owing to its utilization of high-quality imported engineering plastics renowned for their exceptional strength and pressure resistance.
