Always ensure:
• There is sufficient distance between build-up on the tank wall and the fork.
• There is no risk of 'bridging' the level switch forks.
Examples of products that can create 'bridging' of forks and impair performance are
dense paper slurries and bitumen.

Operating temperature and pressure ranges
Ensure the process is operating within the instrument operating temperature and pressure
ranges.
Liquid density requirements
Minimum liquid density is 31.2 lb/ft
Liquid viscosity range
0.2 to 10000 cP (centiPoise)
Solids content in the liquid medium
As a guideline, the maximum solid particle diameter in the liquid process medium is 0.2 in.
(5 mm). Extra consideration is needed when solid particles are bigger than 0.2 in. (5 mm)
and advice should be sought from Emerson.
Foams
In almost all cases, the Rosemount 2160 is insensitive to foams (i.e. does not see the
foam).
However in rare occasions, some very dense foams may be seen as liquid; known examples
of this are found in ice-cream and orange juice manufacturing.
