product description
Viewshine brass water meter (model U-WR) adopts non-contact measurement principle, integrates three wire pulse output (IEC 60405 standard) and adaptive ultrasonic array technology, and achieves ± 0.5% measurement accuracy within R400 dynamic range (EN 14154 certification). Its brass shell with IP68 protection level ensures a service life of over 12 years, reducing maintenance requirements by 83% compared to mechanical water meters.
Brass water meter through 0.01L/min microfluidic detection (industry average 0.05L/min) and M-Bus/LoRaWAN dual-mode communication, the device achieves triple water-saving benefits: precise billing, leakage prevention and control, and analysis optimization.
advantages
Three advantages of Viewshine brass water meter: precise measurement, complete data recording, and equipped with local optical ports
Through ultrasonic technology, precise measurement and real-time billing can be achieved. While monitoring water usage, all relevant data can be fully recorded, achieving water retention. And it can provide alarm prompts for abnormal water usage. The configured optical port enables the water meter to read and record more efficiently.
