This free, downloadable PDF explores the differences between level measurement by means of guided-wave radar systems and differential pressure transmitters. Although DP transmitters presently remain the dominant instrument for level measurement, their worldwide market share is expected to steadily erode in the presence of growing demand for the newer level measurement technologies. Leading the assault is guided-wave radar (GWR), which is among the most versatile of technologies now being used for liquid level measurement. The white paper compares and contrasts the two technologies, and explains the advantages of the guided-wave approach for many applications. The direct link is at http://tinyurl.com/3myh39o.
