inline flow sensor 0.5-10 L/min

KEYENCE FD-Q10C | Digital Inline Liquid Flow Sensor 0.5–10 L/min, PFA Body, NPN Open Collector, M8 Pigtail
KEYENCE FD-Q10C digital inline liquid flow sensor — 0.5–10 L/min range, PFA wetted parts, NPN open-collector pulse output, M8 3-pin connector. For DI water, chemicals, coolants in semiconductor & pharma.

Product Overview

The KEYENCE FD-Q10C​ is a digital inline liquid flow sensor​ from the FD-Q series (Chemically Resistant / Ultrapure Liquid Type), designed for non-contact measurement of low-viscosity liquids in small-diameter process lines. It features a PFA (perfluoroalkoxy) flow tube and wetted parts, making it suitable for deionized water, acids, alkalis, and photoresist solvents in semiconductor and pharmaceutical applications. The sensor outputs an NPN open-collector pulse proportional to flow rate (or alarm via setting switch on amplifier — FD-Q series typically pairs with dedicated FD amplifier such as FD-AMP1 or integrated display unit)​ and connects via an M8 3-pin male connector (pigtail cable). The Q10C variant covers 0.5–10 L/min​ with a one-touch fitting or threaded process connection (typically Rc 1/4" or SUS hose nipple — confirm per regional catalog). No moving parts — flow is sensed via thermal or ultrasonic principle depending on FD sub-family (FD-Q uses thermal micro-sensor array).

Key Features

  • All-PFA Wetted Path:​ No metal contamination — ideal for UPW (ultra-pure water), CMP slurry lines, and corrosive chemical dosing in semiconductor fabs.
  • No Moving Parts:​ Thermal micro-sensor — no paddle/wheel to clog or wear; minimal pressure drop (< 0.02 MPa typical at max flow).
  • Compact Inline Design:​ Fits tight process skid tubing runs — direct inline installation vs. larger turbine meters.
  • Pairs with FD-AMP Amplifier:​ Dedicated amp provides local LCD display, HI/LO alarm relays, analog retransmission, and key-lock — simplifies loop integration.
  • Quick-Disconnect M8 Connector:​ Easy removal for maintenance/calibration without disturbing wiring.

Typical Applications

  • Semiconductor Wet Process:​ Chemical dispense line flow verification (HF, H₂SO₄ dilute, developer — per compatibility chart).
  • Pharma / Biotech Skid:​ DI water or CIP solution flow confirmation in small-bore tubing.
  • Coolant / Lubricant Monitoring:​ Low-flow confirmation on spindle or laser head cooling loops.
  • Chemical Dosing Systems:​ Verify metering pump output on acid/alkali injection lines.
