In the fast-growing smart metering industry, Water Meter Sensor has become the preferred inductive pulse solution for upgrading mechanical water meters and building next-generation smart meters. At the heart of Weifeng’s Water Meter Sensor is the WF8002, our self-developed inductive metering chip, manufactured with advanced wafer-chip technology.
This comprehensive 2026 guide provides everything you need to know about the Water Meter Sensor WF8002 — from technical specifications to real-world integration advantages.
Water Meter Sensor is Hangzhou Weifeng’s industrial-grade inductive pulse output sensor, fully powered by the proprietary WF8002 Metering Chip.
Unlike traditional reed switches or Hall sensors, the WF8002-based Water Meter Sensor offers non-contact detection, delivering reliable pulse signals for both residential and commercial smart water/gas meters.
