Honeywell ST 3000 Installation Guide

4.1 Mounting ST 3000 Transmitter, Continued
High Temperature
Transmitter Mounting
You can mount the high temperature transmitter directly to the process
flange connection or the process piping. Figure 9 shows typical pipe
and flange mounted transmitter installations for comparison.
To mount a flange mounted transmitter model, bolt the transmitter’s
flange to the flange on the wall of the tank or process pipe.
It is the End User’s responsibility to provide a flange gasket and
mounting hardware that are suitable for the transmitter’s service
condition.
Once the transmitter is mounted, the transmitter housing can be rotated
to the desired position. See Table 8, step 4.
ATTENTION
On insulated tanks, remove enough insulation to accommodate the
flange extension.
