Abstract: A measurement apparatus includes an x-ray sensor including an x-ray source having a high voltage power supply for emitting an x-ray spectrum and an x-ray detector for providing a measured x-ray signal value responsive to the x-rays received after transmission through a coated substrate including a sheet material having a coating material thereon. A second sensor is a beta gauge or infrared sensor for providing a second sensor signal that includes data for determining a total weight per unit area of the coated substrate or of the sheet material A computing device receives the measured x-ray signal value and the second sensor signal configured to implement an x-ray based calculation that utilizes absorption coefficients for the coating material and sheet material, the measured x-ray signal value, the x-ray spectrum, and the weight measure as a calculation constraint, for computing at least the weight per unit area of the coating material.

Abstract: An apparatus includes a transmitter configured to transmit a signal including an electromagnetic pulse towards material in a tank. The apparatus also includes a receiver configured to receive a signal including multiple reflections of the pulse. The apparatus further includes at least one processing device configured to process the received signal and determine a measurement associated with the material in the tank. To process the received signal, the at least one processing device is configured to fit multiple models onto the received signal, select one of the models, identify at least one of the multiple reflections in the received signal using the selected model, and determine the measurement using the at least one identified reflection in the received signal. Each model is constructed from a superposition of multiple types of pulse reflections.
