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.
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.
