CREDIT SALES CENTERS AND CREDIT SALES POINTS • Credit loading units where credit sales is performed are Credit Sales Centers and Credit Sales Points (POS). Authorities form credit sales centers with at least 4 credit sales terminals (computers). At these centers credit sales amounts are higher. Credit Sales Points (POS) are consisted of one credit loading computer. Credit sales points are at banks, small shops and entrance of other authority buildings. • Computers with smart card reader and credit loading devices at credit sales points are fully compatible with authority center servers. • When subscriber goes to the credit sales point to buy credit, all information are visible at the sales point computers. After the payment subscriber get his smart card back with load credit. • All computers at credit sales centers and credit sales points are connected to authority central servers. All operations between subscriber and sales unit are transmitted to the central servers by ...

SMART CARDS USED IN THE PREPAYMENT SYSTEM 1) Authority Card ( Used by the authorities ) a- Cancel Card b- Open Card c- Return Card d- Control Card 2) Subscriber Cards Electronic Smart Card 1) AUTHORITY CARDS A) CANCEL CARD : Used when authority decide to close a meter for any reason. In this case subscriber can not use energy or water. In order to activate meter, authority must use Open Card. B) OPEN CARD: On the cases that meter is closed with “Penalty”, “Service” messages, this card is used to activate the meter. After that subscriber may use water. C) RETURN CARD: If the subscriber request the purchased credit amount on the smart card or meter back , this card is used. D) CONTROL CARD: Used by authorities to control all units of the meter periodically. Control card, record all information of meter ( battery level, valve problems etc.) and these information is sent to the service management. 2) SUBSCRIBER CARDS • SUBSCRIBER CARD: The card used by th...

ELEMENTS OF PREPAYMENT METER SYSTEM A - Electronic Meter B - Smart Card C - Credit Sales Points and Data Center A - ELECTRONIC METER Electronic meters are water consumption metering devices consist of semi-conductor components. In the system subscribers make the advance payment prior to water distribution. Purchased credit is loaded to the meter via IC smart card. When credit ends, meter closes itself and cuts off water distribution. • ELECTRONIC CONTROL UNIT The unit that analyses all consumption and status information, controls LCD, closing unit and card reader unit. • LCD SCREEN The unit that displays all information of meter. • CARD READER The interface that smart card is inserted to and provide communication between meter and smart card. Credit is easily loaded to the meter when the smart card is inserted to the card reader unit. After loading the credit, there is no need to leave smart card on the meter. Subscriber should remove the smart card from...

Prepayment System -  Features & Benefits Subscribers and utilities get rid of forgotten payment of bills or follow-up of last payment dates and will have a fixed price guarantee. Subscribers are able to load purchased credits easily to your meters and do not get affected by energy and water price increases. Subscribers may buy as much credit as they want and whenever you want from credit sales points(POS). Smart Card enables information transfer between authority company and the meter. Purchased credit information is transfered from authority to the meter and consumption information is transfered from meter to the authority. Provides a better customer service for the authorities. The word “meter” is used as devices for measuring the amount of energy and water in residential, commercial and industrial facilities accurately. In this traditional definition, features other then metering consumption amounts are not taken into consideration. On the othe...

Product Characteristics & V.S. Prepaid Water Meter - Photoelectric AMR Water Meter Straight reading - Use of photoelectric straight reading technology, delivers direct readout from the dial counter, electronic readout and mechanical readout sustain the same, enabling error-free meter reading.  Non-power supply – The water meter requires no power supply normally, zero - power consumption, instant power supply is required only when reading the meter.  Small calibre water meter uses of 2-wired M-Bus line, regardless of polarity, easy and simple construction; Generally, The bulk meter is battery-powered, and uses of RS485 line for saving electricity’s sake.  Use of decelerating magnatic transmission structure, simultaneously, it improves the driving force of the magnet, eliminating the phenomena of “Step failing out”.  “Step failing out” : When a water meter operates at large flow rate, the lower magnet and the up magnet won't operate in a simultaneous ste...

Technical Indicators of  Photoelectric AMR Water Meter 1. Relative Error: Water Temperature ≦30℃, Max permissible error in low flow rate area is ±5%; Max permissible error in high flow area is ±2%.  Water Temperature >30℃, Max permissible error in low flow rate area is ±5%; Max permissible error in high flow area is ±3%. 2. Temperaturte Class: (0.1～30)℃ for chilled water meter; (0.1～90)℃ for hot water meter 3. Working Pressure: ≤1.0MPa 4. Pressure Loss：≤0.063MPa(DN15-40); ≤0.025MPa(DN50-300). 5. Installation Environment：Class B(DN15-40); Class C (DN50-300). Note ：Water meters with electronic devices can be devided into 3 levels according to the climatic and mechanical environment condition: - Class B:  Fixed water meter installed indoor - Class C: Fixed water meter installed outdoor - Class  I: Portable water meter 6. Electromagnetic Environment：E1-Residential, Commercial and  Industrial. Note :  Water meters wit...

Prepaid Bulk Irrigation Water Meter Overview The product consists of the bulk AMR water meter, the diaphragm leading valve and the controller, is used for measuring the total water volume that flow through the pipeline, with prepayment function accessible. 1. Valve body with self-support type pilot-actuated structure, leading valve can be opened without large torsion, primary valve can be easily opened with the help of water pressure, small power consumption required for valve on/off, can be driven by only one battery, eliminating the problem of no external power supply in the installation environment; 2. Pilot valve uses floating ball valve principle instead of former pin valve structure to ensure no blockage and malfunction with the pilot valve, thousands of normal start-ups are ensured. 3. Pilot valve uses duplex principle, functions when front water pressure drops, back water 4. Primary valve uses American diaphragm valve principle, eliminating blockage of...

Narrowband IoT (NB-IoT) Narrowband IoT (NB‑IoT) is a new way of communicating with “things” that require small amounts of data, over long periods, in hard to reach places. What is Narrowband IoT? Narrowband IoT (NB‑IoT), also known as LTE Cat. NB1, is a Low Power Wide Area (LPWA) technology that works virtually anywhere. It connects devices more simply and efficiently on already established mobile networks, and handles small amounts of fairly infrequent 2‑way data, securely and reliably. And the best is, it provides: very low power consumption excellent penetration coverage lower component costs   NB‑IoT meets the challenges We believe in a wireless future with secure, stable, and robust connectivity. Many potential “connected things” are located in remote or hard to reach areas, at long distances from the next cellular base station. When there is  coverage,  it  is often  poor and requires  the  device  transmitter...
