Second Generation ABS Acoustic Bubble Spectrometer

By DE Editors

Generation II of the Dynaflow, Inc. (Jessup, MD) ABS Acoustic Bubble Spectrometer for the measurement of bubble size distributions and void fractions in gas/liquid mixtures is now available with multiple improvements. 

The data-sampling rate has been increased by nearly five times, which expands the bubble detection limit below 10 microns radius. In addition, all the hardware external to the processing computer has been integrated in one box. Additionally, a laptop configuration is now available using an Express Card port.

The software processing of the Generation II ABS incorporates the latest developments stemming from the past few years of research. In addition to tests in water media, R&D efforts for acoustic bubble detection have been conducted for other media such as biological tissue, mercury, and food (whipped cream and syrup). The resulting improvements in the signal processing have increased the accuracy of the ABS and allows for the processing of noisy signals that would have been discarded by the previous ABS generation.

Dynaflow can provide a system including the ABS instrument, amplifiers, transducers of different sizes, and if needed, transducers embedded in flow pipes or other fixtures. A software-only version of the ABS is also available.
