FUM03 Clamp-On Ultrasonic Flow Meter

Non-Invasive Liquid Flow Monitoring for Industrial, Water, and HVAC Systems

The FUM03 Clamp-On Ultrasonic Flow Meter offers high-accuracy, non-intrusive liquid flow measurement across a wide range of pipe sizes from DN8 to DN40, without cutting pipes or interrupting system flow. Ideal for use in HVAC cooling towers, wastewater treatment, energy monitoring, and process control, the FUM03 delivers ±1–2% accuracy, fast setup, and versatile outputs including analog, RS-485, relay, and pulse.

Engineered for industrial environments, the FUM03 installs in minutes with zero pressure loss or fluid contact—making it a reliable solution for corrosive, dirty, or mission-critical systems.
