1.5 Bolting considerations
If the transmitter installation requires assembly of a process flange, manifold, or
flange adapters, follow these assembly guidelines to ensure a tight seal for
optimal performance characteristics of the transmitter. Only use bolts supplied
with the transmitter or sold by Emerson

Process Management
as spare parts.
Figure 1 illustrates common transmitter assemblies with the bolt length required
for proper transmitter assembly.
