overview
Viewshine Ultrasonic Smart Water Meter, ecological intelligent precision for sustainable water supply network. It uses durable composite materials and cutting-edge IoT connectivity technology to achieve zero mechanical wear and tear operation, with a service life of over 12 years. Its non mobile ultrasound core achieves R800 dynamic range accuracy while eliminating pressure loss and air measurement errors. Certified according to IP68, WRAS, OIML, and MID B+D standards, the compact design supports 360 ° installation in any position and complies with U0/D0 standards.
Key Technical Features
1. Ultra low hydraulic resistance
The optimized flow channel design reduces pressure loss to ≤ 0.025 bar and reduces pump energy consumption by 18% compared to mechanical flow meters.
2. Compact and sturdy casing
The IP68 grade composite shell can withstand a diving depth of 30 meters and is suitable for underground/industrial deployment.
3. R800 expands measurement range
The precision ranges from 0.001L/h micro leakage to a peak flow rate of 15m ³/h, meeting the needs of both residential and industrial applications.
4. Bubble immune leak detection
The ultrasonic algorithm can identify leaks of ≥ 0.5L/h without triggering errors due to airbags or turbid media.
5. Triple data integrity
The LoRaWAN/NB IoT/M-Bus protocol has packet retransmission capability, ensuring 99.999% integrity of billing data.
