B97 VPW Valve Control / Prepaid

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).

Description

The Solution for Addressing NRW

B97 VPW provide an all-in-one smart water meter solution, it offers up to R400 measuring range ratio (Q3/Q1) which is far better than standard mechanical water meter, smaller water flow rate can be measured to help utility collect every drop of water without any waste. By adopting a ball valve B97 VPW is able to perform as a prepayment meter or remotely valve control meter, both approaches bring values to utility by significantly increment of water bill collection.

Compact Design

Integration design of measuring part and bass ball valve in one meter, easy for installation, communication, maintenance, and transportation. B97 VPW can be installed either in horizontal or vertical direction by no loss of measuring accuracy. Water utility can choose IC card prepayment function, or remotely valve control for those who refuse to make water bill payment on time.

Durable Service Period

B97 VPW presents either IP65 or IP68, and its body is fabricated from durable Brass 59-1 material. This robust design makes the B97 VPW maintenance-free and highly precise with extraordinary, durable service period, which could be upto 16 years.
