Displacer Level Transmitter

Mounting
The E3 MODULEVEL transmitter can be mounted to a
tank using a variety of configurations and process connections.
Generally, either a threaded, welded or flanged connection
is used with an external cage. A flanged connection is always
used on a tank top model. For information about the sizes
and types of connections available, see
Model Numbers,
Section 3.7
.
Ensure all mounting connections are in place on the tank
and properly sized for the specific unit being installed.
Compare the model on the nameplate with the product
information to ensure the MODULEVEL transmitter is
correct for the intended installation.
If the MODULEVEL must be insulated, DO NOT insulate
the transmitter head, e-tube or finned extensions.
2.4.1 Tank Top Installation (E3A & E3B)
Figure 5 illustrates a typical tank top installation.
Before installing, ensure that:
• There is adequate headroom for the installation of the
MODULEVEL head and displacer and that it has unob-
structed entry into the vessel.
• Using a level, the mounting flange is level within 3° in all
directions.
• If the adjustable hanger assembly (P/N 32-3110-001) is
used, it is cut to the required length and attached to the
displacer stem.
NOTE: The adjustable hanger assembly is used when the top of the
displacer and, therefore, the top of the measurement range
must be positioned in the vessel more than 9.31" below the
mounting flange. The standard hanger cable length is 8 feet.
Consult factory for longer cable.
