Abstract: An electrical capacitance volume tomography sensor for use in high temperature, high pressure applications for measuring or imaging a flow within the sensor, the sensor comprising an outer pressure vessel, a plurality of electrodes placed within the outer pressure vessel, a plurality of threaded studs, wherein one of the threaded studs is attached to one of the plurality of electrodes, a coating or layer is placed on the plurality of electrodes for electrically isolating the plurality of electrodes, a plurality of holes in the outer pressure vessel for allowing terminal connections to the plurality of electrodes within the outer pressure vessel, wherein each of the plurality of holes accepts one of the plurality of threaded studs, and a plurality of gaskets, where one gasket is placed at each of the plurality of holes to seal the pressure at each of the holes in the outer pressure vessel by placing one gasket concentric around one threaded stud and conforming each gasket between a back of an electrode and the

Abstract: 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.
