Prepaid Water Meter

A split-type, dry-dial prepaid water meter for homes and multi-unit buildings. The customer keeps track of their balance on a separate wall-mounted display (CIU), which talks to the meter wirelessly — so there's nothing to read at the meter itself.

Why clients choose it

• Available in DN15, DN20 and DN25 to suit most residential connections.
• Prepay by token or recharge through the Customer Interface Unit (CIU) — balance shown clearly on an LCD screen.
• Wireless link between meter and CIU (up to 350–400 m), so the display can sit indoors even if the meter is outside.
• Sealed to IP68 — built to keep working in wet or buried installations.
• Lithium battery rated for 4+ years before it needs replacing.
• Low-balance and alarm indication on the CIU, so customers aren't caught out by a sudden cut-off.
