The XY-TEK CG series ultrasonic flow sensors/flow meters provide the biopharmaceutical industry with a non-invasive solution for verifying the performance of fluid pumps in the bioprocessing systems, monitoring pipeline integrity, and facilitating automated, intelligent bioproduction management.
CG series clamp-on ultrasonic flow sensors do not directly contact the fluid being measured, allowing for repeated use without costly disinfection or gamma irradiation. The non-invasive design makes them especially suitable for high-sanitization environments, such as single-use biopharmaceutical systems.
Featuring a compact design, the CG series ultrasonic flow sensors can be easily clamped onto flexible plastic tubing. They enable accurate and reliable measurement of bioliquid without interrupting the existing setup.
Industry Challenges
Contamination
Maintaining hygiene and sterility is critical in biopharmaceutical production Any contaminants introduced during measurement can compromise product quality. Therefore, measurement devices must be non-invasive and easy to clean or sterilize to avoid direct contact with the measured liquids.
Flow Rates
Flow rates can vary significantly due to changes in production cycles, batch sizes, or formulation adjustments. Accurately measuring these variable flow rates requires measurement technologies that can adapt and provide reliable data regardless of fluctuations, ensuring consistent product quality.
Air Bubbles
Air bubbles and particulate matter in the biofluid can interrupt flow and affect measurement accuracy. This is particularly relevant in biopharmaceutical processes where precise dosing and mixing are critical.
Application Overview
XY-TEK cG series ultrasonic flow sensors/flow meters can be used in the following bioprocess:
- Medium Preparation – Buffer Preparation: Replace volume measurement device.
- Bioreactor (Continuous / Perfusion) – Manage the inflow and outlow of fluids.
- Filtration – Control the process conditions during the filtration process.
- Filling Equipment – Measure the volume of fluid filled into the container.
- Cell Inoculation – Controls the injection of cell lines into the reactor
- Centrifuge – Verifies that fluids are flowing
- Chromatography – Balance the amount of acid/base delivered to the system.
By leveraging non-invasive ultrasonic flow sensors, biopharmaceutical manufacturers can achieve high levels of accuracy, reliability, and efficiency in flow measurement processes, ensuring industry stringent compliance and maintaining product quality.
