1.The STS (Standard Transfer Specification) is an Open Architecture initially introduced in South Africa in 1993, for the transfer of electricity prepayment tokens. Subsequently published by the IEC (International Electro technical Commission) as an International standard IEC62055-41,51. Now it also becomes popular for Water & Gas Meters with following advantages:
Compatibility
Inter-operability between system components from different
manufacturers of prepayment systems;
1.2 Easy Data (Water Volume/Credit) Transfer.
Water Credit/Volume transfer via 20 digits Token, no External Data transfer Media (Token-less);
1.3 Flexible Water Purchase (Prepaid Mode switchable to postpaid) that makes it much more convenient and easier.
1.3.1 Flexible Water Purchase Way at appointed agencies via POS or cash, Customer Self-service Mobile Phone via APP, USSD or by E-payment.
1.3.2 Customer self-service via Mobile phone, either through APP
or USSD, by E-payment
STS Prepaid/Postpaid Water Meter System consists of following components.
2.1 Smart Water Metering - Velocity / Volumetric / Ultrasonic .
2.2 Split Customer Interface Unit (CIU) for Meter Recharge & Data
Query- touchable LCD keypad with English language display.
2.3 Hardware & Digital Billing Management System (HDMS) for Water Vending, Monitoring, Data Management & Statistics
2.4 Mobile Water Vending Solution via POS or Mobile Phone with integration to local E-payment Platform and banks
System Components
3.1 STS Smart water meter with LCD Display – LoRa or Lorawan Wireless
Comm Module integrated for meter recharge and data query. Comply with International STS Standard IEC62055-41,51
3.2 Customer Interface Unit (CIU) for Meter Recharge - Integrating LoRa or Lorawan Wireless Com. Module in both Meter and CIU Part, it supports Meter Recharge & Data Query via CIU through RF Wireless Comm. The communication distance is around 100-200m in residential area and should be programmable.
