A new Modality – Ultrasound Tomography System (UST) – m3000u instrument has been developed by Industrial Tomography Systems plc.

The user operation GUI has been developed in conjunction with the ITS m3000 platform. The UST modality can be operated either separately or together combined with the existing ITS m3000 ERT and ECT modalities during an online process.

A screen shot from an online measurement by using the m3000u to detect an object (diameter = 3cm glass bottle) within a UST sensor in diameter = 5.5 cm with 16 transducer electrodes.

It emits a pressure wave into the fluid and to detect it at different location on the vessel surface (the ultrasound time of flight). The frequency of the pressure wave is of the order of MHz.

Experimental UST sensor

  • The determination of the group velocity of the fluid in two or three dimensions. This is related to spatial distribution of the fluid’s density/compressibility.
  • To determine the possible and size of objects within the fluid. These objects may be either solid or gaseous.
  • Ultrasound spectroscopy (USS) provides a host of information on the industrial process. It can provide standard ultrasound analysis based on the compressibility and density of the process material.
  • USS can also provide information of particle or droplet size, this is derived from frequency dependent absorption of the ultrasound wave. The output can be characterized the required material, and so can provide fast identification of when the process product has strayed outside its quality limits.
  • It works on-line with at full concentration, in comparison with other methods such as static light scattering work off-line and require the samples to be diluted.
  • It is intrusive and can be combined with imaging measurement such at electrical resistance/capacitance tomography.
  • Useful for quality control, problem solving, and process product research.

What is Acoustics?

Acoustics is the general science of sound and its interaction with matter. Sound is a microscopic oscillation of the molecules of a material to create a propagating mechanical wave.


What is Ultrasound?

Ultrasound is high frequency sound (above the audible range) which is taken to be greater 20kHz
