Real-time measurement of liquid holdup and electrical conductivity in stratified flow using an ANN-particle filter and conductance sensor
B F de Moura, G M M da Conceição, V C Carvalho, M F Martins, R R Moura, et al.
Measurement Science and Technology, 2025
Accurate measurement of liquid film thickness is crucial for understanding stratified multiphase flows in various industrial applications, such as oil and gas production, chemical processing, and others. Conductance sensors are widely used for this purpose due to their simplicity and cost-effectiveness. However, they often suffer from inaccuracies caused by factors such as contact impedance, electrode polarization, and environmental noise, which can introduce significant measurement errors. To address these challenges, a novel approach combining a particle filter (PF) with an artificial neural network (ANN) was developed to enhance measurement accuracy. The ANN compensates for systematic errors in conductance sensor readings, while the PF incorporates measurement variability to improve the robustness of the estimation process. The proposed method was tested using simulated stratified flow conditions with liquid holdup ranging from 0.05 to 0.7 and electrical conductivities varying between 0.0101 S m − 1 and 0.0508 S m − 1 . Results demonstrated an error margin of ± 10 % for holdup and ± 5 % for electrical conductivity, validating the method’s reliability. This hybrid approach improves measurement precision while maintaining cost efficiency, making it a practical solution for real-time industrial flow monitoring, particularly in environments where conventional methods struggle with accuracy.

Review of Scientific Instruments, 2022
Electrical Resistance Tomography (ERT) has the potentialities of non-intrusive techniques and high temporal resolution which are essential characteristics for multiphase flow measurements. However, high background conductivities, such as saline water in oil extraction, impose a limitation in ERT image reconstruction. Focusing on the operational limits of an ERT tomography system operating in different conductivity backgrounds from 0.010 to 4.584 S/m, the impact on the image reconstruction was assessed via signal-to-noise variance. The signal-to-noise ratio (SNR) variance had a strong correlation ( p-value = 5.40 × 10−15) with the image reconstruction quality at the threshold of 30 dB, reaching a correlation value of r = −0.92 in the range of 0.010–0.246 S/m. Regarding the position error of the phantom, p-value = 1.30 × 10−5 and r = −0.66 were attained. The global results revealed that the correlation of the mean of the SNR ( p-value = 5 × 10−4 and r = 0.55) was kept unaltered through the whole conductivity range, showing that such a statistical index can induce bias in establishing the operational limits of the hardware.

A Methodology to Assist in Improvements of Low-cost Electrical Impedance Tomography Systems
Bruno Furtado De Moura, Adriana Machado Malafaia Da Mata, Marcio Ferreira Martins, Francisco Hernan Sepulveda Palma, Rogerio Ramos
IEEE Latin America Transactions, 2022
Electrical Impedance Tomography (EIT) is a technique that enables the reconstruction of the impedance distributions inside a vessel in a multiphase flow of industrial processes. Such a technique combines a data acquisition (DAQ) system to inject a current and to measure the voltages on the sensors and an inverse problem technique to reconstruct the image properly. This problem is highly ill-conditioned, causing errors to produce instabilities. Therefore, when performing the acquisition, the DAQ system must have adequate accuracy to allow the reconstruction of images with good quality. To avoid these measurement inaccuracies, this paper introduces a methodology that aid in the process of development of low-cost systems. It consists of investigating the errors in the current version of the system. Further, predicting the systematic errors of each subsystem by modeling its frequency response by Simulation Program with Integrated Circuit Emphasis (SPICE). From this information, it is possible to perform critical analysis, aiding design decisions.

A novel methodology to measure the film thickness profile based on current stimulation for two-phase flow
B F de Moura, A M M da Mata, M F Martins, F H S Palma, R Ramos
Measurement Science and Technology, 2021
The film thickness of a two-phase flow is a parameter of interest since it is of importance to the heat and mass transfer phenomena. A novel method is proposed based on electrical impedance tomography (EIT) and conductance sensors to measure this quantity. An analytical equation is developed to relate the differential voltage associated with a current injection on the domain and the angular film thickness profile. A characteristic of the measuring procedure is that it presents a high sensitivity when the thickness is small, with the possibility of adjustment using different magnitudes of current. This model is compared experimentally and by the complete electrode model (CEM), solved by finite elements method (FEM). Results presented a good agreement with the FEM simulations, and the experimental results presented systematic error caused by the fringe effect.
