Description
The YF-C3 is an ultra-compact clamp-on ultrasonic flow meter built around one idea: make measurement easy. Its patented magnetic snap-on bracket is pre-assembled at the factory — just place the unit on the pipe and the clamps self-align and lock magnetically, then tighten four M4 screws. No tools, no coupling mess, no pipe cutting — installation in minutes.
Designed for small to medium pipes (OD 9–277 mm, DN6–DN100+), the YF-C3 is available as an integrated clamp-on unit or a split (remote) version, with standard aluminium-alloy or PTFE-coated anti-corrosion housings, and medium-temperature options up to 120 °C.
