China Prepayment Brass Body Drinkable Water Flow Meter for Residents

Prepayment Brass Body Drinkable Water Flow Meter for Residents
IC card prepaid water meter is the new measuring instrument employing the microprocessor to realize water collection, processing, display and reserving. It is the best choice for realizing intelligent control by most of tap water administrative bureaus, Ideal for enhancing public awareness of saving water. This meter has many patents. Compared with traditional way, it can control user's overspend by prepaying for an IC card

Working Condition:
1.Max water temperature: 40 for cold potable water
2.Max Water temperature: 90 for hot potable water
3.pressure: ≤1.0Mpa

Mainly function:
1. Signal Coolection:
High quality double reed pipe, alternate work method, equivalent to two steady state model, which can effectively prevent measurement error lead by vibrate, backwater, interference of outside magnetic field can be detected at the same time,guarantee the mechanical part and electronic part count, if there are any interference of outside magnetic field, two dry reed pipe, and at the same time, close valve control part start program, prevent theft of water.

2. Pre-paid functions:
Automatically booking quantity by the purchase card, valve will be closed when it up to reservation quantity , realize thepayment first; Have a single price or tiered price double function.

3. Tiered price function:
Water meter charged separately according to presupposed water consumption tiered price.

4. Hoarding limit function:
It cannot recharge when the sum of balance and recharge amount large than the presupposed figure.

5. One IC card comply one meter:
IC card use hardware and software encryption, has the perfect encryption system. User can check the Cumulative water consumption, surplus and the prepaid water quantity etc., and through the IC card to return to the corresponding water meter information to the management system.

6. Anomaly detection:
With the same function like Black box, when strong magnetic interference measurement signal, it will record the date, then close valve.

7. Pre-alarm function:
According to demand to pre set the alarm, water over draft, when it up to limit figure, it will close valve and remind user to buy water.

8. External battery replacement function:
Water meter can replacement battery with left/right direction, very easy to replacement in batch(Battery: ER18505M NA).

9. Regular maintenance of valve:
To avoid the vale cannot normal work because of long time no change, it will open and close one time at Zero in themorning at each 7th , 14th , 21th and 28th .

10. Figure:
The figure inside this water meter will keep more than 10years.

11. Ball valve system,
its pressure loss is lower than the other structure of the valve, and valve drive system torque is generated in the required torque of the valve itself more than three times, more than 300% of the insurance factorcan prevent because of scale formation, long-term need not, the impurity control the consequences of too much.
