Overview
Adopting cutting-edge non-contact ultrasonic detection technology, Viewshine household smart water meter ensures precise flow measurement with broad measuring coverage.
Free of internal moving components, it avoids mechanical abrasion, keeps low pressure loss and maintains steady long-term operation. It can capture extremely low flow down to 2 liters per hour, perfectly fitting domestic water metering scenarios and effectively helping water enterprises cut unaccounted water loss.
