Product Details
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 ℃.
Functions
- Prepaid, avoid owing and consciously refuse to pay bill
- High accuracy of measurement
- Environmental protection material and can guarantee water quality
for drinking
- Programmable tariff set
- Waterproof, moisture-proof and anti-attack
- Adopt replaceable batteries, change batteries by customer
themselves, more convenient.
Key features
- 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
- Electric floating ball valve technique: adopt electric ball valve
technique, work reliably and lower loss of pressure
- 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
- Anti-attack of strong electricity or magnetism: water meter will
close valve automatically when being attacked by strong electricity
or magnetism
- Micro-computer and microstorage technique: high integrated and high
reliability

Installation
- The installation of water meter meets the installation requirements
of ISO4064-2:2005
- The caliber of water meter shall correspond with caliber of pipes
and the used flow rate is less than or close to the permanent
flowrate. The installation place should avoid exposure, flooding,
freeze and pollution, and convenient for installing, removing and
reading data.
- The water meter shall be installed horizontally (display surface is
upward).
- The sands and stones and other sundries in the pipelines shall be
cleared.
- The arrow on the water meter should be the same as the water flow
in the pipeline.
- If the water meter is installed on the inlet of the boiler, it is
better to install inverted valve on the outlet of water to prevent
the return current of hot water and steam will damage the water
meter.
Competitive Advantage:
- Compliance to international standards: ISO4064 / GBT778 /
Q/320700JR05-2003
- Strict process control
- Advanced calibration equipment
- Engineer team
