Non-Contacting Radar Technology Delivers Accurate Liquid Level Measurement in Single-Use Bags

Single-use technologies continue to gain adoption in pharmaceutical manufacturing, helping reduce downtime between batches and increase manufacturing efficiency. However, accurately measuring liquid levels in single-use bags remains a significant challenge. As bags empty, they collapse, wrinkle, and change shape, creating additional echoes that can lead to false radar readings and unreliable level measurements.

These inaccuracies can have serious consequences. Overestimating liquid levels can allow a bag to run dry, while underestimating levels can compromise dosing and impact batch quality. They can also contribute to production disruptions and delays downstream.

In this Ask the Expert article, Rob O'Flaherty, Strategic Account Manager at Emerson, discusses why liquid level measurement remains challenging in single-use bags and explains how Smart Echo Supervision™ in Rosemount™ Non Contacting Radar Level Transmitters helps distinguish true liquid levels from disturbance echoes to maintain reliable measurements throughout the emptying process.
