XY-TEK's CM series ultrasonic clamp-on flow sensors are compact in size, and can measure flow and output results without external circuitry. The sensors can be clamped on rigid plastic tubing, such as PFA, PTFE, Teflon, PVDF, PP and Nylon tubing, to accurately measure the liquid flow rate and detect air bubbles. A silicone or rubber layer is used as the acoustic coupling layer between the sensor and tubing. The sensors are not in direct contact with the liquid in the tubing and will not contaminate the liquid. They are especially suitable for applications where strict hygiene is required, such as bio-pharmaceutical processes and medical equipment. The sensor uses the ultrasonic transit-time difference method to non-invasively measure the liquid flow rate in the tubing. It has high precision and stability, can be used repeatedly without disinfection, and does not bring the risk of cross contamination to the liquid. Standard products are available in a range of sizes to match the common tubing outer diameter. The sensors can also be configured as flow switch, bubble detection or dosing control devices.

Common applications in the field of biopharmaceuticals :

CM series sensors are suitable for various biopharmaceutical processes and equipment :
