Products Description
Viewshine U-WR Home Water Usage Meter : Intelligent Brass Engineering for Residential Water Supply Networks
U-WR is forged from corrosion-resistant brass alloy and advanced ultrasonic metrology technology, providing unparalleled precision through a zero motion component architecture. Compared to mechanical flow meters, its optimized hydraulic design reduces pressure loss by 95%, while solid-state sensors eliminate wear and tear during over 12 years of maintenance free operation. No rotating components ensure an accuracy of ± 0.5% drift (R400 dynamic range) under all flow conditions (from micro leaks to peak demand), ensuring billing integrity and reducing non revenue water usage.
