Common Advantages & Selection Guide
Common Advantages: All clamp-on models support no pipe cutting/non-stop installation; No moving parts/electrodes, anti-fouling and maintenance-free; Compatible with metal/resin/PVC and other common industrial pipes.
Selection Logic: Match by pipe diameter → flow range → medium (gas/liquid) → environment (temperature/protection) → function (clogging/alarm).
Frequently Asked Questions
Can I install it without cutting the pipe?
Yes, clamp-on design, no pipe cutting or shutdown needed.
Does it work on dirty/viscous liquids?
Yes, non-contact, no moving parts, works with most liquids including cooling water, oil, chemicals.
How accurate is the KEYENCE FD sensor?
Typically ±0.5% F.S. or ±2.0% RD, stable even with minor fouling.
What pipe materials are supported?
Metal, resin, PVC, stainless steel—most common industrial pipes.
Do I need to calibrate it often?
No, auto-calibration and stable design mean long-term use with little maintenance.
Can it measure gas flow?
Some FD models support air/gas; check specs for your medium and range.
What output signals are available?
Analog, pulse, RS-485, IO-Link, alarm output—easy to connect to PLC/SCADA.
Is it resistant to water/dust?
IP65/IP67 rated, suitable for factory and harsh environments.
Can it detect small leaks or low flow?
Yes, wide turndown ratio and high sensitivity for micro-flow and leak detection.
How long does installation take?
Usually a few minutes per sensor—clamp, set pipe size, start measuring.
