The FS8-WJ splash-proof flow switch is an insert-type flow switch that is installed on water flow pipes ranging from 1 to 6 inches and is used to detect water interruption or low flow.
This manual describes the FS8‑WJ splash‑proof flow switch, a compact sensor designed to detect flow interruptions or low flow in water pipelines. It explains the sensor’s principle of operation, which uses a paddle and a micro‑valve to generate an ON/OFF output signal when flow changes.
The document includes installation guidelines, electrical connection details, dimensional data, and performance specifications such as maximum operating pressure, temperature range, and supported voltage levels. Safety notes and part numbers for replacement components are also provided. This manual is written in Chinese.
| Supported voltage | 115VAC, 230VAC, 115VDC, 230VDC |
