Considerations before installation

The Rosemount 3100 Series may be used for level and volume measurement in
open or closed tanks, or open channel flow measurement.
The glass-filled nylon housing version of the transmitter must be installed in a
location where it is protected from ultraviolet radiation to prevent long term
degradation of the plastics used e.g. shrouded from direct sunlight.

Safety considerations

1. Installation must be carried out by suitably trained personnel in accordance
with the applicable code of practice.
2. If the equipment is likely to come into contact with aggressive substances, it
is the responsibility of the user to take suitable precautions that prevent it
from being adversely affected, thus ensuring that the type of protection is
not compromised.
Aggressive substances are acidic liquids or gases that may attack metals or
solvents that may affect polymeric materials.
