Smart Water Meter With Mechanical Sealed Valve(Blue Color)
Application: Jingcheng IC card prepaid water meter is the new measuring instrument employing the microprocessor to realize water collection, processing, display, and reserving. It measures the volume of cold (hot) water passing through the pipeline.
Features:
1. IC card water meter use pre-paid way to achieve the new management mode of “Purchase first, then use ”.
2. Show the different level price of the water. one card can be used to several meters.
3, Double reading display: mechanical and electronic reading.
4. The unique battery protection.
5, Low power consumption. long life time.
6. Prevent outside magnetic interference
7.Valve will shut down for warning when the remaining water is less than the warning limitation, and the valve will open up when inserting the card; Valve will termly shut down and open up automatically to prevent rust.
8. The system saves a lot of manpower, and accelerates cash flow, helps to control the non-recoverable charges and do away with the due payment.

Attachment
With every water meter(threaded ends), there will be two couplings, two nuts, two coupling gaskets and two meter spud thread protectors.
Note: To protect the meter spud threads, store the meter with thread protectors in place.
With every water meter (flanged ends), there will be two flange gaskets.
If you need the connecting flanges (two pieces),
Compliance with standard
Technical data conforms to class B of the ISO 4064 standard.
