After unremitting efforts, exploration and research, the new version of valve control/ prepaid meter, B97 VPW, has been released. It combines the characteristics of industrial products and artworks, and is practical, attractive, precise and durable. The B97 VPW has proven to be a reliable, fully mature breakthrough product in precision measurement and valve control.
In addition, the special compact design does completely assure the quality of water-proof protection. This proof is guaranteed even if it is installed under water in a long time. Moreover, the core engineering concept of B97 VPW aims at cutting down the budget on overall operating costs from remote meter readings. It also helps utility enhance its cash flow by collection of none-revenue-water (NRW).
