3.3 Review mounting considerations
Before installing the Rosemount 3308 Series Transmitter, consider recommendations for
sufficient free space, mounting position and special needs for non-metallic tanks.
3.3.1 Recommended mounting position
When finding an appropriate mounting position for the transmitter, the conditions of the tank
must be carefully considered. The transmitter should be mounted so that the influence of
disturbing objects is reduced to a minimum. For easy access to the transmitter make sure that it
is mounted with sufficient service space.
Figure 3-1. Mounting Position
The following guidelines should be considered when mounting the transmitter:
 Do not mount close to inlet pipes.
 Do not mount close to agitators. If the probe can move to within 12 in. (30 cm) away
from an agitator, the probe should be anchored. See “Anchor the probe” on page 30 for
more information.
 If the probe tends to sway due to turbulent conditions in the tank, the probe should be
anchored. See “Anchor the probe” on page 30 for more information.
 Avoid mounting close to heating coils.
 Position the probe such that it is subject to a minimum of lateral force.
 Make sure the probe does not come into contact with the nozzle or other objects in the
tank.
