The KEYENCE FD-Q10C is an external clamp-on ultrasonic flow sensor designed for non-intrusive liquid flow measurement. Unlike inline flow meters, this unit clamps directly onto the exterior of existing piping without pipe cutting, fluid contact, or process shutdown during installation. It supports two standard pipe specifications: 1/4" (8A, Ø13–16 mm) and 3/8" (10A, Ø16–18 mm), compatible with both metallic and resin tubing materials.
