    "description": "<p>Collected data refer to gas flow modulation measurements in a D=100 mm bubble column. The axial holdup wave is determined at three axial positions using different sensing stategies (gamma-ray densitometry, differential pressure sensors, transmittance optical probes and conductivity needle probes). Average gas holdup as well as amplitude damping and phase-shift have been determined at three different gas flow rates in the homogeneous regime. A description of the experimental setup is provided in the file &quot;Experimental_setup.pdf&quot;. An overview of the performed experiments is provided in the Excel file &quot;DataDescription.xlsx&quot;</p>",
