Split Keypad Water Prepaid Meters With Lora Connection And STS Compliant Standard For Easy Installations

Tanzanian Split Keypad Prepaid Water Meters: LoRa Connection and STS Certification R100 In Tanzania, an innovative split keypad prepaid water meter is gradually changing the way residents pay for water. This water meter adopts advanced LoRa wireless communication technology and follows the STS (Standard Transfer Specification) certification standard R100, providing users with unprecedented convenience and security.

System Composition and Working Principle The system consists of two parts: the water meter (Meter) and the Customer Interface Unit (CIU). The water meter is installed outdoors, while the CIU is placed indoors for easy operation by the user. Both communicate via RF LoRa technology, ensuring stable communication even at a visual distance of up to 1 mile.

Convenient Water Purchase: Consumers can enter water purchase tokens on the CIU, and the token information is immediately transmitted to the water meter via LoRa to complete the recharge process. This simplifies the water purchase process, allowing residents to easily purchase the required water volume. Transparent Inquiry: The CIU is equipped with an LCD display, allowing users to conveniently view various data of the water meter, including token acceptance/rejection records, account balance, historical water consumption, and more. This transparency enhances user trust and satisfaction. Tamper-Proof Design: Since the water meter and CIU are separate, and communication is based on the secure LoRa protocol, any operation on the CIU does not affect the data accuracy or operating status of the water meter itself, effectively preventing tampering and fraud.

Social Impact This split prepaid water meter not only improves the convenience of residents’ lives but also promotes the rational use of water resources. It provides a reliable income protection tool for water supply companies while also bringing a more transparent and efficient water management experience to users. By reducing unnecessary waste and supporting precise billing, this water meter helps build a more sustainable urban water management system.

In summary, Tanzania’s split keypad prepaid water meter, combining modern communication technology and strict security standards, aims to improve people’s quality of life while promoting the digital transformation of public services. Its unique design and functions will undoubtedly have a positive impact on local communities.
