Levelflex M FMP40 FOUNDATION Fieldbus
The following diagrams show typical loads for frequently occuring bulk solids as reference
values. The calculation is performed for the following conditions:
• Suspended probe (probe end not fixed at the bottom)
• Free-flowing bulk solid, i.e. mass flow. A calculation for core flow is not possible. In the event
of collapsing cornices, considerably higher loads can occur.
• The specification for tensile forces containes the safety factor 2, which compensates for the
normal fluctuation range in pourable bulk solids.
