B97 VPW, a next - generation valve control/prepaid water meter. Blending industrial functionality with artistic design, it excels in practicality, aesthetics, accuracy, and durability.
The B97 VPW represents a fully mature innovation in precision measurement and valve control, the valve which is incorporated inside the water meter can be remotelly controlled from the software or even by the Handheld Unit.
A groundbreaking remote valve control ultrasonic water meter, designed to revolutionize the market. Combining unparalleled precision and meticulous engineering, this innovative device features a built-in ball valve and advanced wireless transmission capabilities, enabling seamless remote valve control. It has no moving parts, a visual (LCD) display with meter reading output, and no reverse flow measurement, while being tamper-proof and unaffected by grit and particulates. Battery status can be displayed on water meter LCD, Valve status/Leakage alert/Reverse flow alert can be displayed on LCD and visualized from control and command dashboard.
Furthermore, it enables partial valve opening and closing at specified percentages, providing a compliant solution for regions where regulations prohibit complete valve shut - off.performance.
