Flow sensor SONOFLOW® CO.56 Pro V2.0

medicalultrasonic

Overview
The hybrid flow-bubble sensors SONOFLOW® CO.56 Pro V2.0 combine accurate flow measurement and reliable air bubble detection in liquid-filled medical tubing. These non-invasive, contactless clamp-on sensors enable simple integration, can be clamped onto tubing without any media contact, and are designed to meet high safety requirements for medical technology. Integrated electronics and on-board processing provide a very small footprint.
