Our Ultrasonic Flow Sensors

Precision, Reliability, and Customization for Every Application.

CS series Clamp-on Ultrasonic Flow Sensors / Flow Meters

The CS series clamp-on ultrasonic flow sensor/flow meter is compact in size and does not require an external circuit system for measurement and output. The sensor can be directly clamped onto the outside of a rigid plastic pipe to accurately measure the liquid flow rate inside the pipe and can detect bubbles and large solid impurities in the liquid.

The sensor does not come into direct contact with the liquid in the pipeline and will not cause contamination, making it particularly suitable for scenarios with high hygiene and cleanliness requirements, such as in biological pharmaceutical processes, medical equipment, and new energy for liquid flow monitoring. We have a series of standard-sized products suitable for common pipeline sizes, and we can also customize for users’ special requirements. The sensor can be equipped with flow switches, bubble detection, and filling functions.

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.”
