Discover PFUW, the clamp-on ultrasonic flow sensor for liquids. Measure flow without contact, avoid leaks and pressure loss, and monitor water, oil, chemicals and more with one device.
Measure liquid flow accurately without compromising your process
In modern manufacturing, controlling liquid flow is essential to ensure product quality, process stability and operational efficiency. However, traditional in-line flow sensors often create limitations that impact performance, maintenance and flexibility.
When sensors are in contact with fluid, they can introduce risks, increase costs and reduce reliability, especially when working with different or aggressive liquids.
Common challenges engineers face:
- Risk of leakage, clogging or contamination due to invasive sensors
- Limited compatibility: different sensors required for water, oil or chemical liquids
- Pressure loss affecting process efficiency
- Complex installation requiring pipe modification and machine downtime
- Inability to measure low flow rates accurately.
These limitations make it harder to optimise processes and adapt production systems.
PFUW series – Clamp-on ultrasonic flow sensor, non-invasive monitoring
The PFUW series is a clamp-on ultrasonic flow sensor designed to measure the flow rate of liquids from outside the pipe, without coming into contact with the fluid.
This approach transforms how flow monitoring is implemented making it simpler, safer and more versatile.
Key benefits:
Measure liquid flow without contact
Non-invasive ultrasonic technology measures from outside the pipe, eliminating pressure loss, leakage, clogging and contamination, with no pipe modification required
Use one sensor for multiple liquids
Monitor water, oil, chemical liquids, antifreeze, beverages and hot fluids up to 90°C, increasing flexibility across different machines and processes
Install easily on existing piping
The clamp-on mounting only requires two screws, enabling fast retrofit, reduced downtime and simpler installation than traditional clamp-on flow sensors
Monitor accurately from low flow rates
Reliable measurement starting from 0 l/min, ideal for cooling circuits, process fluids and industrial utility lines
Access real-time data and simplify integration
Integrated display and IO-Link communication provide real-time flow monitoring, easy configuration and faster diagnostics
User-friendly display
A 128x128 dot-matrix LCD with dual-screen view displays multiple parameters at once for more information at a glance, while 90° rotation ensures clear visibility and easy visual checks from any installation angle.
