The STW36-B is an advanced split-type prepaid water meter engineered to redefine efficient water management for residential, commercial, and large-scale utility applications. Compliant with STS standards and certified by ISO9001/ISO14001, this meter combines high-precision metering, robust durability, and intelligent connectivity to deliver a user-friendly and reliable solution. Equipped with LoRa RF wireless technology, it enables seamless real-time data transmission, allowing water supply departments to monitor usage trends, optimize resource allocation, and enhance operational efficiency remotely.
Featuring an IP68 protection rating, the meter is fully waterproof, rainproof, and humidity-resistant, ensuring stable performance in harsh environments. Its construction boasts high-strength flame-retardant ABS thick-walled housing and a precision brass main body with corrosion-resistant threaded joints, guaranteeing leak-free operation and long-term durability. The dry-dial design paired with a transparent meter cover facilitates easy reading, while the independent battery compartment with detachable 3.6V lithium battery (ER18505, 4000mAh) offers over 4 years of service life and hassle-free replacement.
The meter integrates a suite of intelligent functions, including tamper detection (auto-valve closure upon magnetic interference), decade-long consumption data logging, configurable credit alarms, emergency overdraft support, and multi-tariff capability (up to 3 tiered rates). Paired with a compact Customer Interface Unit (CIU) supporting 300-400m wireless communication, it enables convenient recharge via on-site points, third-party platforms (e.g., M-PESA, Alipay), or door-to-door mobile vending units—all generating a 20-digit token for secure activation. Compatible with STRON’s AMI solution and DCU data concentrators (up to 900m communication radius), it seamlessly scales from household metering to city-wide water supply projects, backed by Microsoft SQL Server data security and API integration for personalized expansions.
