Radar technology is increasingly viewed as the best method of level measurement, but this isn’t necessarily true for every application. Radar sensors have certainly made great advancements in performance, accuracy and even cost, but they are not a one-size-fits-all solution and should not be treated like one. In this Q&A, Endress+Hauser's level expert, Scott Peterson, provides an in-depth comparison of the technologies.
