B39 VW-M launched by BOVE combines years' experience in metering research and
development, adopting state-of-the-art technology and sophisticated production. It has
been proven that B39 VW-M is reliable and absolute matured achievement in high
accuracy measurement. In which B39 VW-M is designed with multiple ultrasound
principle to match various demands.
In addition, the special compact design does completely assure the quality of water-proof protection. The accuracy is guaranteed even if it is installed under water in a long time. Moreover, the core engineering concept of B39 VW-M aims at cutting down the budget on overall operating costs from remote meter readings (AMR).
