Viewshine 20mm Water Meter: Precise Intelligence for Sustainable Living.
This advanced ultrasonic flowmeter is designed specifically for multi unit residences and integrates three line pulse output technology, providing unparalleled long-term stability and accuracy. It surpasses mechanical alternatives, promotes water conservation through particle consumption tracking, achieves cost-effective billing, early leak detection (≥ 2L/h), and reduces waste, while also cutting operating costs.
Key Technical Features
1. R400 expands dynamic range
Through R500/R800 certification, precise measurement of fluctuating traffic is carried out to ensure billing accuracy from trickle down to peak demand.
2. Bidirectional U0/D0 traffic tracking
Detect and record backflow events for comprehensive consumption monitoring and revenue protection.
3. Microflow sensitivity (minimum 2L/h)
Ultrasonic sensors capture the minimum usage amount (such as a dripping faucet) with an accuracy of ± 1%.
4. Solid state anti-interference ability
Not affected by water impurities or ≤ 100mT magnetic field, ensuring reliability in polluted or high EMF environments.
5.12 year drift free lifespan
Non mechanical design eliminates wear and extends the lifespan of mechanical instruments by three times.
6. Omnidirectional installation
Vertical/horizontal installation flexibility adapts to complex pipeline layouts.
