Long Lifespan
The pipe section of B39 VW-M is crafted from cast iron, treated with a highly corrosion-resistant electrophoretic baking finish. Paired with it's IP68 - rated protection, it can operate steady in harsh environments for extended periods. It's robust battery setup enables the water meter to function continuously for 10-16 years under wireless communication. This significantly enhances the efficiency of water management.
Unique Design
The B39 VW-M features two sets of transducers. This design enables it to accurately meter water even under special conditions like insufficient water pressure. The transducers, thanks to their unique construction, minimize the deposition of impurities from water on their surfaces.
Additionally, after long-term immersion in severely poor-quality water, the transducers can be replaced. Whatsmore, a pressure sensor can be installed for water pressure monitoring.
Outstanding Performance
Achieving an accuracy of R500, it provides excellent measurement for urban and industrial water applications. With an IP68 waterproof rating, it withstands harsh environments. Boasting a sensitivity of UODO, it can be installed anywhere, ensuring water metering in diverse scenarios.
Multiple Connection Interfaces
B39 VW-M supports multiple communication interfaces, both wired and wireless, ensuring seamless adaptability to different installation environment, such as M-Bus, RS485, Pulse, 4-20mA, LoRaWAN, Sigfox, NB- IoT, GPRS, 4G, wMbus, LoRaWAN+wMbus, etc.
