Sanitary Assembly (FLT93-C)
The instrument is inserted into the process connection with a removable clamp fittings. The Removable Clamp (RC)
sanitary assembly contains a removable clamp connection to the flow element. The Clean-In-Place (CIP) sanitary
assembly has the flow element directly welded into the process stand pipe. Otherwise these instruments function
exactly the same as an FLT93-F or FLT93-S. See Appendix A for an outline dimensions of the instruments.
Figure 2-4 also shows the sanitary assemblies.

Install and Wire the Enclosure(s)
Caution: In applications where the sensing element is located in an explosive environment, isolate the conduit
before it leaves the environment. A potting Y may be used to provide the isolation.
Pulling wires can cause damage to the control circuit. Therefore, remove the control circuit from the
enclosure and use extreme care when pulling wires into the enclosure.
Mount and wire the control circuit either locally or remotely (option) by following the local or remote enclosure
procedure below.
Minimum Wire Size
Table 2-1 shows the smallest (maximum AWG number) copper wire that is used in the electrical cables. Use a lower
gauge of wire for less of a voltage drop. Contact FCI concerning greater distances than those listed in the table. The
sensing element cable must be shielded. If the cable is spliced the shield wire must be continued through the splice.
If a terminal block is used, the shield must have its own terminal.
