Overview
Viewshine's composite ultrasonic water meter adopts a solid‑state design without any moving parts, delivering consistent long‑run performance ideal for multi-unit residential communities. Built to last over 12 years, it sustains dependable metering round the clock.
Leveraging non-contact sensing technology, it maintains precise readings across a wide flow range. The absence of internal moving components greatly reduces mechanical wear, pressure drop and routine maintenance work. Capable of detecting ultra-low flows starting from only 2 L/h, it helps water utilities spot hidden small leaks quickly and cut water loss.
