Our Ultrasonic Flow Sensors

Precision, Reliability, and Customization for Every Application.

CG Series Clamp-on Ultrasonic Flow Sensors / Flow Meters

CG series ultrasonic clamp-on flow sensors / flow meters are compact in size, and can measure flow and output results without external circuitry.

The flow sensors/ flow meters can be directly clamped on flexible plastic tubing to accurately measure the liquid flow rate and detect air bubbles. The flow sensor / flow meters 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 biopharmaceutical processes, medical equipment, and battery manufacturing equipment and industrial automation.

Product Features

High Accuracy: ±3%

The flow rate measurement accuracy is essential for applications requiring stringent quality control and process optimization.

Hygienic Safety

The non-invasive measurement reduces the contamination risk and makes it ideal for sensitive applications in the pharmaceutical industries, ensuring safety and compliance with health regulations.

Bi-Directional Flow Measurement

Support accurately calculating fluid volume and detecting air bubbles. Additionally, it can perform volume dosing and function as a flow switch, providing a multifunctional solution that enhances operational versatility.

Compact Design

The embedded circuit eliminates external wiring, streamlining installation and reducing space requirements. This design simplifies setup while maintaining high performance.

No Blockages

Designed to operate without blockage or dead zones, enables smoother fluid flow and reduces potential system strain.

Output

CG series ultrasonic flow sensor/flow meters offers multi-output methods that facilitate seamless integration with existing systems.
