The VEGAPULS 69 provides accurate level measurement of bulk solids at distances up to 120 meters. This is possible because of its 79 GHz frequency. Its focused, reliable 79 GHz frequency ignores distractions like internal installations & buildup on the vessel wall, much like the VEGAPULS 64 does for liquids. As a result, the VEGAPULS 69 is more precise than other level measurement systems that operate at lower frequencies.
