Abstract

Thermography is a powerful tool for locating or verifying levels in tanks and silos. But one could ask “Why bother?” All too often existing level indication instruments are simply not reliable or positive verification of instrumentation readings is required. When properly used, thermography can reveal not only the liquid/gas interface, but also sludge buildup and floating materials such as waxes and foams. Similar techniques can be used to locate levels and bridging problems in silos containing fluidized solids. This paper discusses the parameters and limitations that must be addressed, shows techniques that can be employed, and illustrates the discussions with numerous thermal images.
