Installation
Evaluate the site selected for the Transmitter installation with respect to the process
system design specifications and Honeywell’s published performance characteristics
for your particular model.
Temperature extremes can affect display quality. The display can become unreadable
at temperature extremes; however, this is only a temporary condition. The display will
again be readable when temperatures return to within operable limits.
Mounting the Transmitter
Transmitter models, except flush mounts and those with integral flanges, can be
attached to a two-inch (50 millimeter) vertical or horizontal pipe using Honeywell’s
optional angle or flat mounting bracket; alternately you can use your own bracket.
Flush-mount models are attached directly to a process pipe or tank by a one-inch
weld nipple. Models with integral flanges are supported by the flange connection.

Bracket Mounting
Optional mounting bracket, see Figure 2
Existing mounting bracket, see Figure 3
Rotate the transmitter housing, see Figure 4
Level a transmitter with small absolute or differential pressure spans, see Figure 5
Optional Mounting Bracket
Position the bracket on a 2-inch (50.8mm) and install “U” bolt around pipe and
through holes in bracket. Secure with nuts and lock washers provided.
