overview
Viewshine Water Sub Meter has revolutionized urban water resource management through seamless IoT connectivity and machine learning analytics. These MID certified (MI-003) instruments are designed specifically for municipal networks and high-density residential areas, providing an accuracy of ± 0.3% within the R400 dynamic range (0.5-40m ³/h) and a leak detection accuracy of 0.2L/h. Its sturdy IP69K rated housing can withstand extreme urban environments, while the integrated LoRaWAN/5G module enables real-time area metering area (DMA) monitoring, which has been proven to reduce NRW by 28% in smart city deployments.
Key Technical Features
1. Intelligent dynamic range adaptation
Adopting ISO 4064 Class 1 certified R800/R400/R500 with three dynamic ranges (0.01-50m ³/h) and ± 0.5% accuracy, covering the full scenario measurement needs from dripping to peak water use.
2. Revolutionary installation optimization technology
The U0/D0 fluid dynamics design breaks through traditional limitations, reducing the demand for straight pipe sections by 80%, supporting vertical/horizontal/inclined multi-directional installation (± 30 ° tolerance), and adapting to the renovation of old pipe networks and space limited scenarios.
3. AI enhanced microfluidic monitoring
Equipped with neural network algorithms, it achieves 1.5L/h level leakage identification (24-hour warning), combined with M-Bus optical interface to export real-time water usage mode analysis reports, helping water companies reduce 22% of non revenue water losses.
4. Extreme environmental durability system
The IP68/IP69K dual protection certified housing has passed 1000 cycles of testing from -30 ℃ freezing to+90 ℃ steaming, combined with 316L stainless steel transducers, achieving a 15 year maintenance free operation commitment and reducing maintenance costs by 60% compared to mechanical meters.
5. Smart Water Service Ready Architecture
Pre installed LoRaWAN/NB IoT module slots, supporting seamless integration with AMI systems according to MID MI-003 standards. Historical data storage can be extended up to 10 years and continuously meets the EU Ecodesign 2027 energy efficiency regulations through OTA upgrades.
