overview
The Separate Water Meter For Tenants is an ultrasonic water meter designed specifically for residential use by VIEWSHINE. It comes in three different sizes, SN15/DN20 and DN25, to meet various residential water needs. It also adopts the latest exterior design, ensuring both aesthetics and quality control. The zero moving parts reduce internal wear and maintain high-precision operation, which is 8 years longer than the lifespan of ordinary mechanical water meters.
Key Technical Features
1. Intelligent dynamic range adaptation
R800/R400/R500 dynamic range ensures accuracy in all flow scenarios from 0.5L/h micro leaks to peak consumption surges
2. Hydraulic Dynamics Optimization
The U0/D0 flow optimization design eliminates 80% of traditional straight pipe requirements and achieves multi axis installation (vertical/horizontal/angle ± 30 °) for enclosed spaces and aging pipelines. Compared to traditional instruments, the installation time has been reduced by 40%.
3. Leakage management driven by artificial intelligence
Network algorithm detects 1.5L/h leakage within 24 hours
Integrate M-Bus optical ports to reduce non revenue water by 22% in municipal deployment
4. Extreme environmental resilience
IP68 rated housing can withstand 1000 thermal cycles (-26 ℃ to+60 ℃)
Compared to mechanical instruments, 15 years of maintenance free operation can reduce lifecycle costs by 60%
5. Preparation for Smart Cities
Pre installed LoRaWAN/NB IoT slot for instant AMI integration (compliant with MID standards)
10-year data history with cloud synchronization function
