Clamp-On Flow Monitoring with SMC's PFUW Sensor
When adding a flow sensor requires pipe cutting, shutdowns, or downtime, it’s more than just a hassle—it’s a cost. That’s why the SMC PFUW Series Clamp-On Flow Sensor is such a game-changer. In this hands-on demo, Amos Hunter, Application Engineer at Ramco, walks through how the PFUW sensor brings precision flow monitoring to any system—without interrupting your process.
LFlow Sensing with Zero Downtime
LoTraditional inline flow sensors require plumbing modifications and system shutdowns to install or replace. The PFUW changes the game with a non-invasive clamp-on design. Using simple band straps and two screws, the sensor can be installed in minutes, making it ideal for:
- Retrofitting existing systems
- Applications with limited maintenance windows
- Plants that prioritize uptime and cleanliness
Once installed, the sensor securely monitors the flow of liquids—without ever contacting the fluid inside the pipe.
What Can It Detect?
The PFUW is compatible with a wide range of pipe materials and liquid types, including:
- Water
- Oils
- Antifreeze
- Chemicals
- Beverages
- High-pressure fluids
This versatility makes it a strong fit for industries like food and beverage, HVAC, chemical processing, and manufacturing.
Key Performance Features
LAmos’s demo highlights just how capable the PFUW sensor is, even in a simple hot water application.
In the demo, Amos sets the sensor to switch a discrete output when the flow exceeds 2 GPM, triggering a red-to-green indicator light—showcasing how easy it is to integrate the sensor into visual or control-based feedback loops.
Here’s what sets it apart:
Flow rate detection from 0 to 26 gallons per minute
No clogging or pressure drop, since there’s no contact with the liquid
No contamination risk or material compatibility issues
Digital color display with customizable orientation and contrast
Outputs include analog (1–5 V, 4–20 mA), discrete PNP/NPN, and IO-Link
Real-time visibility of flow rate, accumulated volume, setpoints, IO-Link status, and more
Smart Integration, Standalone or PLC-Based
The PFUW’s wide output support—including IO-Link—makes it easy to tie into existing PLC systems or operate as a standalone monitor. IO-Link compatibility also opens the door for remote configuration, diagnostics, and predictive maintenance.
With its flexible mounting, broad compatibility, and intelligent data output, the PFUW fits seamlessly into both new and legacy systems.
