HOW TO USE
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 IC card on the induction area of
water meter 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
continue to use water by swiping 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.

INSTALLATION
1) The installation of water meter meets the installation requirements of ISO4064-2:2005.
2) The caliber of water meter shall be based on the size
of the pipeline and the usual used water flow is no more than common flow of
the water meter; and the installation location shall be avoided insolation,
flooding, freezing and pollution, and convenient for installation, removing and
reading data..
3) The water meter shall be installed horizontally (display surface is upward).
4) The sands and stones and other sundries in the pipelines shall be cleared.
5) The arrow on the water meter should be the same as the water flow in the pipeline.
6) If the water meter is installed on the inlet of the
boiler, shall install check valve on the outlet of water to prevent the return
current of hot water and steam from damaging the water meter.
DIMENSION
1) Dimension of dry type water meter
2) Dimension of wet type water meter
Note:
L1---Length of the water meter
L2---Length of the meter and the joints
L3---Effective length of the threaded connection
H---Height of the water meter
W---Width of the water meter
D---Nipple joint
MAIN TECHNIQUES
1) Contactless IC card (RF card) technique: adopt our company’s 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, working 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 micro-storage technique: high
integrated and high reliability.
