As a guideline, the maximum solid particle diameter in the liquid is 0.2 in. (5 mm).
Extra consideration is needed when dealing with particles bigger than 0.2 in. (5 mm).
Consult the factory for advice.
In almost all cases, the level switch is insensitive to foams (i.e. does not see the foam).

However, on rare occasions, some very dense foams may be seen as liquid. Known examples of this are
found in ice-cream and orange juice manufacturing.
