CG Series Clamp-on Ultrasonic Flow Sensors

The CG series clamp-on ultrasonic flow sensors are compact in size, enabling efficient flow measurement and output without external circuitry.

They can be easily clamped onto flexible plastic tubing for precise liquid flow rate measurement and air bubble detection.

The non-invasive measurement technology makes the CG series ultrasonic flow sensors ideal for applications with stringent hygiene requirements. Their versatility makes them well-suited for medical devices with flow rate measurement requirements, such as ：

·Heart-lung machines (HLM)

·Extracorporeal membrane oxygenation (ECMO)

·Organ perfusion & systems for organ transportation

·Dialysis devices, hemodialysis, peritoneal dialysis

·Blood pumps, contrast media injection pumps, etc.
