Note
If alternate drainage is provided by the user, and a small performance loss is acceptable, the instrument could be mounted in 90
degree rotational increments around the pilot shaft axis. The LCD meter may be rotated in 90 degree increments to accommodate
this.
The digital level controller and torque tube arm are attached to the sensor either to the left or right of the displacer, as
shown in figure 2‐5. This can be changed in the field on the 249 sensors (refer to the appropriate sensor instruction
manual). Changing the mounting also changes the
effective action, because the torque tube rotation for increasing
level, (looking at the protruding shaft), is clockwise when the unit is mounted to the right of the displacer and counter‐
clockwise when the unit is mounted to the left of the displacer.
All caged 249 sensors have a rotatable head. That is, the digital level controller can be positioned at any of eight
alternate positions around the cage as indicated by the position numbers 1 through 8 in figure 2‐5. To rotate the head,
remove the head flange bolts and nuts and position the head as desired.
