If the bubbles are below the threshold it is displayed to the user as microbubble activity. When a bubble equal to or greater than the threshold is detected an audio and visual alarm is generated and the arterial pump is stopped, this effectively terminates the cardiopulmonary bypass. The operator must identify and remove the bubble before ...
Air bubbler systems contain no moving parts, making them suitable for measuring the level of sewage, drainage water, sewage sludge, night soil, or water with large quantities of suspended solids. The only part of the sensor that contacts the liquid is a bubble tube which is chemically compatible with the material whose level is to be measured.
Gargamelle was a heavy liquid bubble chamber detector in operation at CERN between 1970 and 1979. It was designed to detect neutrinos and antineutrinos, which were produced with a beam from the Proton Synchrotron (PS) between 1970 and 1976, before the detector was moved to the Super Proton Synchrotron (SPS).

As antibubbles can be easily created at home, they have attracted attention from popular science magazines. [7] [8] Just as soap bubbles, with air inside and air outside, have negative buoyancy and tend to sink towards the ground, so antibubbles, with water inside and air outside have positive buoyancy and tend to rise towards the water surface ...
Thus one can deduce how much mass has the ribbon acquired upon being exposed to air flow; knowing the drain velocity, actual particle mass concentration in air could be assessed. The radiation source can be a gas chamber, filled with 86 Kr gas, or a pieces of 14 C-rich polymer plastic, such as PMMA. [2] [3] Detector is simply a Geiger–Mueller ...

Average bubble diameters of 0.9 mm are possible nowadays, using special polyurethane (PUR) or special recently developed EPDM membranes. [3] Fine bubble diffusers have largely replaced coarse bubble diffusers and mechanical aerators in most of the developed world and in much of the developing world. The exception would be in secondary treatment ...
