Clamp-On Ultrasonic Flow Meter

Compact. Modular. Integrator-friendly.

The V2.0 model is designed for upstream and downstream monitoring in the bioprocess industry. The innovative sensors have integrated electronics which allow them to function without an external board or transmitter, resulting in a compact flow meter in the size of a small transducer. The ultrasonic devices ensure scale-up from process development to commercial applications in GMP environments.

Highlights:

• Reliable flow measurement from 20 mL to 200 L / min
• Accuracy of up to 1 % when adjusted for customer specific tubing / fluid
• Ideally suited for silicone, TPE, and most standard bioprocess tubing
• Real-time flow measurement
• Volume totalizing and dosing output switch
• Integrated electronics, no external transmitter required
• Stainless steel models offer built-in informational screen (no interactivity, for viewing flow rate and volume only)

GMP-ready. Touchscreen enabled.

The V3.0 clamp-on ultrasonic flow meter combines outstanding measurement accuracy over a wide flow range and highest clamp-to-clamp repeatability. The compact SONOFLOW CO.55 V3.0 flow meters with integrated electronics are suitable for applications ranging from process development through GMP to fill and finish operations.

Highlights:

• Reliable real-time flow measurement from 5 mL / min to 180 L / min
• Measurement accuracy of 1% even at lowest flow rates
• Excellent clamp-to-clamp repeatability for standard bioprocessing tubing
• Non-contact design preventing any media contamination and shear stress on cells
• GMP-friendly stainless steel housing with intuitive color touch display
• Volume totalizing and dosing output switch
• Stable measurement unaffected by bubbles and different pressure conditions
• Configuration via SONOTEC software
• Integrated electronics, no external transmitter required

Best for GMP manufacturing, fill/finish stations, labs needing local visual access.

Supports a wide range of standard tubing sizes from 1/32″ to 1″, including:
