SERVO GAUGE USING RAMAN SPECTROSCOPY FOR STORAGE TANK APPLICATIONS

摘要

An apparatus includes a servo gauge. The servo gauge includes a displacer configured to be raised and lowered within material in a tank. The servo gauge also includes at least one light source configured to illuminate a sample of the material at the displacer. The servo gauge further includes at least one detector configured to measure radiation that has interacted with the sample of the material at the displacer. In addition, the servo gauge includes an analyzer configured to perform Raman spectroscopy analysis of measurements from the at least one detector and identify at least one characteristic of the material.
