  • Application limits

    DK < 1.6
    Reduction of the max. possible measuring range due to:
    Media with poor reflective properties cone of repose
    extremely loose surface of bulk solids, e.g. bulk solids with a
    low bulk density during pneumatic filling
    buildup, especially of moist products.
    Alternative for these applications: FMR67B
