Overview
Designed for apartment buildings and shared residential complexes, this Viewshine Smart Water Meter for Apartments offers dependable performance throughout its 12+ year service life. Its ultrasonic measurement principle maintains accuracy as flow rates change, and because there are no mechanical parts to wear out, pressure loss and maintenance needs stay low. With the ability to sense flows down to 2 L/h, it gives utilities an early warning for minor leaks, helping reduce overall water loss.
