Products Description
Main Features
1. Precision measurement system
The integrated R400/R250 dynamic range ultrasonic technology can achieve an accuracy of ± 0.5% and detect flow rates as low as 2L/h. Triple shielded sensors can resist impurities/magnetic interference (EN 14154 certification).
2. Space optimization installation
The U0/D0 hydraulic design eliminates the requirement for straight pipes and supports vertical/horizontal installation in spaces<300mm. The IP68 level structure ensures a service life of over 12 years.
3. Intelligent water analysis
Store 36 months of usage data (capacity/events/alerts) and configurable retention period. M-Bus optical ports support real-time data extraction through standard IEC 61107 tools.
4. Durability engineering
The brass valve body structure can withstand a pressure of 2MPa with a pressure loss of<0.03MPa. Corrosion resistant sensors maintain performance over 200000 operating cycles.
5. IoT Ready visibility
High contrast LCD displays real-time flow/temperature. The optional LoRaWAN module upgrade to AMI network reduced NRW by 18% in on-site testing.
