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.
