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
MAIN TECHNIQUES
1) Contactless IC card (RF card) technique: adopt our companys patent technique of RF card, transmitting data by wireless way, waterproof, moisture-proof and anti-attack.
2) Electric floating ball valve technique: adopt electric ball valve technique, work reliably and lower loss of pressure.
3) Totally sealed design: all the circuits are sealed by high performance casting glue, so there is no exposed electrode, and can be used in moist environment.
4) Anti-attack of strong electricity or magnetism: water meter will close valve automatically when being attacked by strong electricity or magnetism.
5) Micro-computer and microstorage technique: high integrated and high reliability.
