The new proposed method involved subdivision of the pipeline cross-section into many subdivisions called the computational mesh. The subdivision is made by the application of the Finite Element Method (FEM). On each of the electrodynamic sensor installed to detect the electric charges carried by the moving solid particles; the effect of the particles’ electric charges enclosed in each of the computational mesh is modelled into a system equation.
