CS Series Clamp-on Ultrasonic Flow Sensors
CS series clamp-on ultrasonic flow sensors are compact and can measure flow and output results without external circuitry. The sensors can be clamped on rigid plastic tubing, such as PFA, PTFE, Teflon, PVDF, PP, and Nylon tubing, to accurately measure the liquid flow rate and detect air bubbles.
A silicone or rubber layer is used as the acoustic coupling layer between the sensor and tubing. The sensors 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 bio-pharmaceutical processes and medical equipment.
The sensor uses the ultrasonic transit-time difference method to non-invasively measure the liquid flow rate in the tubing. It has high precision and stability, can be used repeatedly without disinfection, and does not bring the risk of cross-contamination to the liquid. Standard products are available in a range of sizes to match the common tubing outer diameter. The sensors can also be configured as flow switches, bubble detectors, or dosing control devices.
Features
- High precision and high stability
- Non-invasive measurement, no direct contact with liquid, hygienic safety
- Bi-directional measurement, can calculate fluid volume, detect air bubbles, perform volume dosing, and function as flow switches
- Circuit embedded in the sensor and no external circuit is required
- No blockage, no dead area, low fluid pressure loss
- Provide standard output methods to seamlessly integrate with customer systems
- Customized calibration of plastic tubing material, size, temperature, and liquid type
Applications
- Medical devices such as hemodialysis machines, organ transplantation systems, heart-lung machines, blood pumps, syringe pump
- Biopharmaceutical processes and equipment, such as fermenters, cell culture equipment, vaccine production, tangential flow filtration systems, liquid chromatographs
- Food & beverage processing, such as milk, juice, and beer production
- Filling equipment, spraying equipment, cooling system, lubrication system
