Prepaid multi jet water meter, RF type IC card, with built in ball valve to control


Our prepaid water meter is 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 ℃.


The built in ball valve control, RF type IC card prepaid water meter, are for commercial water supply. It 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.
