  DYNAFLOW's ABS acoustic foam spectrometer measures the bubble size distribution and the pore flow rate of gas and liquid. It can not only measure the gas volume fraction in the liquid but also the bubble size distribution. This difficult-to-measure characteristic is very important in many fields. For example, there are a large number of bubbles in the ocean at a depth of ten meters. The acoustic characteristics are affected by scattering signals and noise. In the simulation of chemical or biological processes, the control of bubble size distribution is also very important. This method is used in processing such as garbage disposal and Aeration system design and other liquid processes are also very beneficial.

  
  

  Cavitation is the formation of steam and gas filled foam or cavity in the liquid phase, usually due to sudden changes in pressure. For example: when this happens, the flow path along a pump or a propeller blade can have a dramatic effect to affect the equipment In particular, cavitation affects the performance and operation of the propeller. The collapse of hydrofoil and pump cavitation bubbles causes a lot of physical damage and considerable noise. The distribution of bubble nuclei strongly affects the tendency of cavitation.

  
  

  This is especially important if the customer conducts a large-scale experiment, which must correctly control the bubble nucleus distribution and change in the liquid. Measuring the bubble distribution, visually or optically, was difficult and impossible in the past, especially when dealing with a large system and a non-transparent In addition, it becomes more and more difficult to distinguish small particles, small bubbles, and bubbles are more sensitive sonic particles. Therefore, this product can easily pick out small bubbles of liquid without the need for optically transparent liquids or structural organization.
