In the smart metering industry, reliable pulse output solutions are critical for upgrading mechanical meters. Water Meter Sensor is Hangzhou Weifeng Intelligent Technology’s industrial-grade non-contact inductive pulse sensor module, designed specifically for smart water meters and gas meters. At its core is the WF8002, Weifeng’s self-developed metering chip.
This article clarifies the difference between the two and explains their respective roles.
Water Meter Sensor is a complete non-contact inductive pulse output sensor module. It detects the rotation of a metal target (usually an impeller or magnet holder inside the meter) through electromagnetic induction and outputs standard pulse signals without any physical contact.
This non-contact design brings major improvements over traditional solutions:
The WF8002 is Weifeng’s proprietary metering chip, developed in-house with wafer-chip level manufacturing technology.
Important clarification: While the Water Meter Sensor is the complete inductive sensing module (non-contact pulse output), the WF8002 is the dedicated metering chip inside it. It handles the core signal processing and pulse generation with high precision and ultra-low power consumption.
By mastering the chip design and manufacturing, Weifeng maintains full control over performance, consistency, and long-term supply reliability.
