Air in Tube Detector

Our ultrasonic detector is designed to detect the presence of air or liquid in a tube. It operates non-invasively, ensuring no contact with the product and maintaining the integrity of the fluid path. The detector works effectively with all types of tubes, even those that are not transparent. This makes it ideal for processes involving single-use fluid paths, eliminating additional costs.

The detector can be seamlessly integrated into control systems to measure output and trigger responses in various processes. These include Chromatography, where it prevents air from being pumped into the column; Depth Filtration, where it detects the end of a batch; Tangential Flow Filtration, where it determines the end-point of fed-batch or buffer additions; and Bioreactors, where it monitors feed lines to notify if addition sources are empty. We also offer a model that can be directly integrated into a pump to shut off when air is detected. Choose our ultrasonic detector for efficient and cost-effective process management.
