Electrical capacitance volume tomography (ECVT) is a non-destructive developed technology that provides a 3D imaging and characterization of various multi-phase flow systems and industrial processes. ECVT is a revolution of the traditional 2D electrical capacitance tomography (ECT) technology imagining principle. The ECVT retrieves 3D volumetric images through its capacitance measurements.[1]

Principles

ECVT reconstruct a volume image of various materials in the imaging domain through utilizing nonlinear distributions of electric field lines.

The ECVT system consists of the following components 

  • ECVT sensor,
  • Data acquisition system,
  • Computer for data recording and image reconstruction.[2]

Advantages

The ECVT technology provides low profile and flexibility of capacitance sensors, an increase in the number of imaging frames per second, and relatively low cost. These features moved the technology to the top of the list as a tool that could be used in industrial imaging.[3]

Applications

ECVT is applied for multi-phase flow systems measurements. The ECVT would provide Measurements in real-time in a three-dimensional components of multi-phase reactors. The ECVT could be applied to gas-liquid and gas, gas-solid fluidized bed, gas-solid circulating fluidized beds, liquid-solid bubble columns, and multi-phase flows in vessels with complex geometries.
