XFT Clamp-On Ultrasonic Flow Meter: Accurate Flow Measurement Without Pipe Modification

Thu 23.07.2026

The XFT Series ultrasonic flow meter from Gems Sensors delivers accurate flow and temperature measurement without cutting pipes or shutting down the system. Its non-invasive clamp-on design, maintenance-free operation, and broad pipe compatibility make it an ideal solution for industrial, commercial, and HVAC applications.

Non-Invasive Flow Measurement Without System Downtime

Installing a flow meter often requires pipe modifications, fluid draining, and costly downtime. The XFT Series ultrasonic flow meter eliminates these challenges with a clamp-on design that mounts externally on the pipe without cutting, drilling, or interrupting operation. This makes it suitable for both new installations and retrofit projects. 

No Moving Parts, No Pressure Loss

The XFT uses ultrasonic technology and contains no moving parts. As a result, it introduces no pressure loss, experiences no mechanical wear, and eliminates the risk of contaminating the process fluid. This design also reduces maintenance requirements while improving long-term reliability.

Wide Pipe Compatibility

The flow meter supports pipe sizes from 16 to 52 mm (3/8" to 1.5"), providing flexibility across a wide range of industrial and building-service applications. Its compatibility with various pipe materials simplifies deployment in existing systems.

Integrated Flow and Temperature Monitoring

In addition to flow measurement, the XFT provides integrated temperature measurement with an analog temperature output. This allows users to monitor two critical process parameters using a single device.

Easy Integration into Control Systems

The XFT features MODBUS® RTU communication and analog output options, enabling seamless integration into PLC, SCADA, and building management systems. A full-color rotatable LCD display provides convenient local monitoring and improved visibility regardless of installation orientation.

Designed for Industrial and HVAC Applications

The combination of non-invasive installation, maintenance-free operation, and modern communication capabilities makes the XFT well suited for:

• HVAC systems
• Industrial cooling circuits
• Process applications
• Commercial buildings
• Retrofit installations
• Systems where downtime must be minimized

Conclusion

The XFT Series Clamp-On Ultrasonic Flow Meter offers a practical solution for accurate flow and temperature monitoring without modifying existing piping. Its clamp-on installation, zero pressure loss, maintenance-free design, and MODBUS RTU connectivity make it an excellent choice for modern industrial and HVAC systems.
