The STS prepaid water meters are a type of prepaid water metering system based on the STS (Standard Transfer Specification) protocol, widely used in regions such as Africa and Asia for water utility management. STS prepaid water meters allow users to pay in advance before using water, which improves the cash flow efficiency of water utility companies and helps users manage their water usage budgets more effectively.
·Reduce Financial Risks: Pay before use to minimize revenue risks for water utilities.
·User Self-Management: Monitor water usage in real time to avoid billing disputes.
·Tamper-Proof: Encrypted TOKEN and closed-loop system prevent unauthorized manipulation.
·Low Power Design: Battery life typically lasts 6-10 years
