摘要： A system and method for imaging, monitoring, or measuring systems and processes utilizing only data provided from capacitance sensors. The present invention combines the multi-frequency method of both ECVT/AECVT and DCPT to image or measure processes and systems more efficiently and accurately than the methods alone. The present system analyzes capacitance and current phase acquired at multiple frequencies to determine a plurality of properties of single and multiphase systems all at once. The combined use of ECVT and DCPT in multiphase flow can also be extended to measure volume fraction and phase distribution of flows involving greater than three phases by using multiple frequencies for capacitance, current phase, or both.

摘要： The present invention uses a plurality of magnetic field sources and magnetic field sensors mounted against a surface. Based on the mass of ferromagnetic material, such as steel, the magnetic field sensors detect variable magnetic field strength and this variance is proportional to the mass of ferromagnetic material being detected. An electronic device reads the magnetic field values and uses the information to quantify the ferromagnetic material in the surface or inside the volume of the construction component.
