SONOFLOW® CO.55 Clamp-On Ultrasonic Flow Meter

High-Performance Non-Invasive Flow Monitoring for Sterile Manufacturing

At Fluid Biosolutions, we specialise in providing advanced instrumentation that supports the manufacture of sterile pharmaceutical products. One of our flagship offerings is the SONOFLOW® CO.55 Clamp-On Ultrasonic Flow Meter – a non-contact, highly accurate flow measurement solution designed for flexible tubing systems in the biopharmaceutical and life sciences industries.

If you’re seeking an ultrasonic flow meter that delivers precision, sterility, and scalability across all stages of drug manufacturing, the SONOFLOW CO.55 is the ideal choice.

What Is an Ultrasonic Flow Meter?

An ultrasonic flow meter is a device that calculates flow rate using the transit-time principle. By sending and receiving ultrasonic waves through the wall of a tube, the device measures how long the wave takes to travel with and against the flow. The time difference reveals the velocity of the liquid, which is then used to calculate the total flow volume.

Unlike traditional flow meters, clamp-on ultrasonic flow meters are entirely non-invasive. They don’t require fluid contact, eliminating contamination risk and simplifying validation in GMP-regulated environments.

Overview of the SONOFLOW CO.55 Clamp-On Sensor

The SONOFLOW CO.55 was purpose-built for non-contact flow measurement in flexible tubing. As a clamp-on ultrasonic flow meter, it’s particularly well-suited for single-use bioprocessing, fill-finish operations, and drug development applications.

SONOTEC Ultrasonic Sensors for Non-Invasive Flow Measurement

The non-invasive measurement of flow rates in fluid-filled tubing is essential across a wide range of scientific, industrial and regulated environments. SONOTEC’s ultrasonic flow sensors are relied upon globally in bioprocessing, pharmaceutical manufacturing, medical science, automation technology, mechanical engineering and hydraulic system design, where precise, contamination-free monitoring is critical.

SONOTEC’s SONOFLOW® sensor series is engineered to deliver fast, accurate and repeatable flow measurement in flexible tubing systems. Because these ultrasonic sensors operate using a clamp-on, non-contact design, the process fluid never interacts with the device, making the technology ideal for applications with strict hygiene, GMP compliance and sterility expectations.

Designed for single-use bioprocessing, sterile manufacturing, cleanroom operations and high-precision R&D environments, SONOFLOW sensors enable real-time flow monitoring without interrupting production or compromising product integrity.

Pumps & Sensors for Bioprocessing | Precise Flow and Monitoring Solutions

Efficient, accurate fluid control and real-time monitoring are vital in modern biopharmaceutical manufacturing. At Fluid Biosolutions, we deliver advanced pumps & sensors engineered for sterile, single-use systems and GMP-regulated environments. Whether you’re managing media and buffer preparation, fill-finish operations or closed-loop automation, our solutions provide the precision and reliability your process demands.

Why Pumps & Sensors Matter in Bioprocess Manufacturing

A robust bioprocess relies on two foundational elements: the correct delivery of fluids and rigorous monitoring of critical parameters. Pumps ensure controlled movement of liquids – such as media, buffer, reagents or final product – while sensors provide accurate real-time data on flow, temperature, pressure, conductivity and more. Together, they underpin closed-system bioprocessing, minimise contamination risk, and enable consistent yield and quality.

Industries from cell & gene therapy to large-scale fill-finish use these tools to maintain operational integrity, scale effectively and meet regulatory standards.

Common Applications in Upstream & Downstream Processes

By properly combining the right pump and matched sensor, you gain improved process control, less manual intervention, and stronger traceability – critical in regulated manufacturing.

What to Look For: Key Features of Modern Pumps & Sensors

  1. Compatibility with Single-Use Systems
    Choose pumps and sensors that integrate seamlessly with disposable tubing and assemblies, reducing cross-contamination risk and simplifying validation.
  2. Accurate Flow & Monitoring Data
    High-precision sensors (for example, ±2% accuracy) deliver reliable readings for volume, rate, pressure or temperature.
  3. Cleanroom-Ready, GMP-Compliant Design
    Low particulate generation, easy clean or replaceability, compact design and documented performance are must-haves for regulated environments.
  4. Flexible Integration & Connectivity
    Look for sensors with both analogue and digital outputs (4-10mA, 0-10V, Modbus, RS-485) and pumps that interface with control systems for closed-loop automation and traceability.
  5. Built for Reliability & Validation
    Whether your process is research-scale or full production, devices should offer strong repeatability, low maintenance and clear validation documentation.
