HIGHLIGHTS
  • Combination of two types of electrical tomography (capacitance and impedance).
  • Verification of the advantage of hybrid tomography over homogeneous methods.
  • Application of the LSTM network to solve the inverse problem in electrical tomography.
  • The original approach to tomographic measurements as a data sequence for the LSTM network.
KEYWORDS
ABSTRACT
The article presents a new concept for monitoring industrial tank reactors. The presented concept allows for faster and more reliable monitoring of industrial processes, which increases their reliability and reduces operating costs. The innovative method is based on electrical tomography. At the same time, it is non-invasive and enables the imaging of phase changes inside tanks filled with liquid. In particular, the hybrid tomograph can detect gas bubbles and crystals formed during industrial processes. The main novelty of the described solution is the simultaneous use of two types of electrical tomography: impedance and capacitance. Another novelty is the use of the LSTM network to solve the tomographic inverse problem. It was made possible by taking the measurement vector as a data sequence. Research has shown that the proposed hybrid solution and the LSTM algorithm work better than separate systems based on impedance or capacitance tomography.
