Radar level videos
This three-minute video, "VEGAPULS 69—media with small grain sizes/radar level measurement" by Jürgen Skowaisa and Clemens Hengstler of VEGA Greishaber KG, shows how smaller-wavelength sensing can make finer particles appear larger. It's one of a series of videos on radar level sensing issues and solutions.
