Philadelphia Mixing Solutions,Ltd.’s(PMSL’s) ITS Resistive Tomography System

Electrical Resistivity Tomography (ERT) or Electrical Resistivity Imaging (ERI) is a geophysical technique for imaging sub-surfaces structures from electrical measurements made at the surface. This technique was modified by Industrial Tomography Systems for mixing applications

The sensor grid extracts quantitative information from a mixing vessel like blending pattern, blending time, suspended solids behavior and distribution of solids, distribution of air bubbles, and in general flow information in mixing of opaque media. This is extremely important for verification and validation of mixing performances. It adds another level of sophistication to PMSL technical expertise.
