Prepaid IC Card Large Caliber Ultrasonic Water Meter

OVERVIEW:

Prepaid IC card large caliber ultrasonic water meter is separate structure, composed by FS smart water meter and FS-2 controller.

The controller can be installed in a convenient place with wireless connection to facilitate user to manage their consumption more easily.

The FS-2 controller built-in microcomputer, customers purchase water volume at vending points and upload water volume by swiping his IC card on the induction area of the controller. FS smart water meter adopts advanced ultrasonic measuring technology, used for measuring water flow passing through pipelines and regularly upload total water consumption wirelessly to controller, which will subtract the used water volume accordingly. When water volume is used up, controller will close valve to stop water supply.

There is an optional function of setting for daily limited water volume. If finished daily limited water volume, water meter will close valve whatever whether there is water remains in the controller.

FS-2 controller will open valve automatically on the next day to supply same daily limited water volume again.

FUNCTIONS

1. Prepaid function. User can open valve and get water supply after swipe the purchased card on the controller.

2. Infrared communication function. The meter’s data can be set by hand-held unit.

3. Wireless data interactive function. The meter and the controller can be interchange data at multi time interval, to make sure the meter info’s reliability and timeliness.

4. Historical data storage function. It can store latest 18 month of water consumption, which is convenient for user’s inquiry and statistic.

TECHNICAL PARAMETER

DIMENSION:

1) Dimension of FS water meter (DN40)

2) Dimension of FS water meter (DN50～DN300)

3) Dimension of controller DN40

4) Dimension of controller DN50-DN300

MAIN TECHNIQUES:

1) Alarms when voltage is low.

2) Automatic data correction technology.

3) LCD display, with high definition and wide temperature range.

4) Flow rate has 8 levels and are separately adjusted, with high precision.

5) Ultra-low energy consumption (static power consumption is less than 7uA).

6) The tube adopts forging technology.

7) Measuring mechanism has no moving parts and no wear and tear forever. Maintain 100% accuracy for its lifetime.

8) There is optic electric interface, adopt infrared tool can read meter.

9) Pre-alarm tech of flow sensor: when the communication is unmoral or destroyed maliciously, the controller can recognize it and close valve automatically to avoid waste of water.
