Prepaid IC card water meter Multi jet dry dial pure brass DN15 - DN25 RF type
Smart prepaid water meter adopts a contactless IC card to store
water volume and monitor water consumption. Customers purchase
water volume at vending points and upload water volume by swiping
his IC card on the induction area of installed water meter inside
or outside home to activate valve, which will open automatically to
supply water.
During the period of water supply, the built-in microcomputer of
water meter will automatically check and subtract the used water
volume. Water meter has twice alarm function, when the purchased
water volume reaches to alarm volume, water meter will close valve
and stop water supply. Customer can resume water supply by swiping
his IC card on water meter. When the remain water volume is used
up, water meter will stop water supply completely and the customer
needs to charge his IC card again.
Available in sizes 15mm to 25 mm with nominal flow rates of Qn 1.5m³/h to Qn 15m³/h. It's for cold water volumetric measurement, or hot water up to 90 ℃.
