Maybe it's all those crystal-clear highballs and free-flowing beverages that make level measurement seem conceptually simple to uninformed observers. However, when they sober up and peer into pitch-black tanks and silos with internal structures, mixers and agitators that must handle viscous and volatile fluids, solids and slurries—not to mention the build-up, dust, vapor, foam and other conditions they generate—well, let's just say accurate level measurement in the real-world is a whole different ballgame. These challenges have been met by generations of inventive operators, process engineers, system integrators and suppliers, who have developed an array of…
