Clamp-on flow meter CM series

ultrasonicvolumefor water

Product Overview
The CM series clamp-on ultrasonic flow sensors / flow meters are compact, non-invasive devices with embedded electronics. They attach to flexible plastic tubing to measure liquid flow rate and detect air bubbles and large solid particulates. As the sensor does not contact the fluid, CM models are suitable for hygienic or contamination-sensitive environments such as medical devices, biopharma, food & beverage, industrial automation and laboratories.

Applications
Blood purification devices: heart-lung machines (HLM), ECMO (Extracorporeal Membrane Oxygenation), organ perfusion ,organ transportation devices, CRRT, circulation devices.
Dialysis devices: hemodialysis, peritoneal dialysis for real-time flow monitoring and early warning of blockages or air bubbles.
Blood pumps and contrast media injection pumps: accurate flow measurement for pump verification and imaging delivery control.

Product FeaturesProduct Features

• High Accuracy

CM sensors provide precise flow measurement across each model range, enabling process control and quality-sensitive applications where accurate volumetric data is required.

• Hygienic Safety

Non‑contact measurement reduces contamination risk, making CM sensors appropriate for medical, biopharma and food processing lines where fluid integrity is critical.

• Multi‑function Detection

In addition to flow and volume measurement, CM sensors detect air bubbles and can be used for dosing verification and as a flow-switch in system automation.

• Compact Integrated Design

Embedded circuitry eliminates the need for external wiring and simplifies installation on production or test lines where space and fast deployment matter.

No Blockages
External clamping avoids in‑line obstructions and dead zones, ensuring continuous measurement without interrupting the fluid path.

Sensor Calibration
Calibration can be tailored to tubing material, dimensions, temperature and liquid type to optimize accuracy for specific installations.
