overview
This series of Water Submeters For Apartments adopts Doppler ultrasonic sensing technology, integrates NB IoT/LoRaWAN dual-mode communication modules, and realizes real-time monitoring of water use data through the Viewshine management platform, supporting various remote control and viewing systems. The Water Submeters For Apartments has passed MID certification and is suitable for drinking water pipe network metering scenarios, reducing the NRW (non revenue water) ratio by 18-22%.
Products Highlights
1. Adaptive measurement architecture
The Water Submeters For Apartments selecting R400/R500/R800 dynamic range and adopting U0/D0 hydraulic design eliminates 95% of straight pipe requirements.
2. Ultra sensitive leak proof
The minimum detectable flow rate is 1.5L/h (validated by Appendix A of EN 14154), using bubble discrimination algorithm. The analysis of usage patterns driven by artificial intelligence reduced NRW by 20% through early leak alerts (SMS/email).
3. Maintenance free operation
Non mechanical ultrasonic measurement (0.3% annual drift), IP68 dual rated housing.
Military grade PVC-U material (certified by 16 bar MAP/EN 12201) ensures a service life of 12 years.
4. Intelligent Connection Kit
Use integrated M-Bus interface. 365 day data recording (volume/temperature/pressure) with OTA firmware updates.
5. Life cycle cost optimization
Compared to mechanical instruments (DN15-DN40 applications), TCO is reduced by 40%.
