The Pixact Bubble Monitoring (PBM) system is designed for the online analysis of bubble suspensions and foams in industrial processes. The measurement is based on the direct optical imaging of the suspension combined with advanced image analysis. The images of the suspension are processed in real time with powerful analysis algorithms for statistics such as bubble size distribution and its derived values, including mean bubble size, standard deviation, the Sauter mean diameter and parameters of cumulative distribution (D10, D50, D90, etc.).


See Benefits for customer reviews and benefits provided by the Pixact systems.

See Products for details on the technology utilized in the Pixact systems.

Two configuration options are available for PBM: the Pixcell flow-through cuvette for installation on process lines or dedicated sampling lines and the Pixscope probe for installation in reactors and tanks.


The PBM technology can be used for measuring both foams with high air content and bubble suspensions with lower air content. The foundation of PBM is the live image view of the suspension, which provides the operator with valuable visual information on the process.

The proprietary image analysis algorithms of the measurement system detect bubbles and other particles in the image data and produce detailed real-time numerical information on their characteristics and other suspension properties.

Measurement results produced by PBM include

  • Bubble size distribution and related statistics, such as Arithmetic, Sauter and volumetric mean diameter, and percentiles of cumulative distribution (D10, D50, D90, etc.)

  • Bubble count

  • Bubble concentration

  • Bubble flow velocity

  • Analysis of flotation cell performance

  • Analysis of aeration and other mass transfer processes

  • Analysis of foam properties and homogeneity

  • Detection of gas in the process stream
