FS1-W is a splash-proof flow switch that can be installed on a 1/2-inch process pipe to detect flow or low flow. Its operating flow rate can be adjusted with a flow rate adjustment screw.
The FS1‑W is a single‑hole, high‑sensitivity splash‑proof flow switch designed for installation on 2‑inch process pipelines to detect flow interruptions or low flow rates. Its sensing element consists of a flow orifice and a flap that actuates a magnetic micro‑switch, offering high reliability and long life.
The manual includes the device’s specifications such as maximum operating pressure, temperature range, weight and certifications, as well as installation requirements (1/2" NPT internal thread, horizontal pipe mounting) and wiring details for the micro‑switch contacts. This manual is written in Chinese.
