Overview
Viewshine's Digital Ultrasonic Water Meter adopts a moving-part-free structure to deliver dependable long-duration performance, ideal for multi-family residential installations. The meter is engineered with a service life exceeding 12 years for stable operation. Its non-contact sensing technology maintains precise measurement over an extensive flow range. Without any moving internal components, mechanical abrasion, pressure drop and maintenance requirements are greatly reduced. It is capable of capturing tiny flows starting from 2 L/h, enabling water authorities to spot minor leaks at an early stage and curb water wastage.
