Our Ultrasonic Flow Sensors

Precision, Reliability, and Customization for Every Application.

CPD series Clamp-on Ultrasonic Flow Sensors / Flow Meters

The CPD series clamp-on ultrasonic flow sensors/flow meters adopt an integrated design, with a built-in display and circuit system. It can directly measure the flow rate and intuitively read the monitoring data.

The ultrasonic flow sensors/flow meters can be directly clamped onto the outside of a rigid plastic pipe to accurately measure the liquid flow velocity within the pipe. The accuracy can reach ±2%, and it can also detect bubbles and large solid impurities in the liquid.

Product Features

Repeatability: ±0.1% F.S.

Engineered for exceptional accuracy and long-term stability, ensuring reliable performance in demanding environments.

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

Bidirectional measurement, capable of calculating fluid volume, and featuring bubble detection function

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

Offers standard output protocols, allowing for quick, effortless, and seamless integration into customer’s existing control systems.

Case in Industrial Automation

Automated Dosing Systems

In the fine chemical industry—whether it is the micro-dosing of flavors and fragrances, the continuous injection of polymer additives, or chemical treatment in industrial water systems—production processes are shifting from “manual valve adjustments based on experience” to “data-driven precision control.”
