The above precautions are minimum requirements to be used. The complete use of ESD precautions can be found in
the U.S. Department of Defense Handbook 263.
Verify Serial Numbers (For Remote Applications Only)
Verify that the flow element serial number matches the control circuit serial number. A tag indicating the serial
number is located on the local and remote enclosures. The serial number is also found on the control circuit.
Verify Installation Location
Prepare the vessel for installation, or inspect the already prepared location to ensure that the instrument will fit into
the system. Prepare the necessary sealants or gaskets to provide a leakproof installation for the application if
required. The location that should have been prepared at the time of order should be at least 20 pipe diameters
downstream and 20 pipe diameters upstream from any bends or interference in the process pipe or duct to achieve
the greatest accuracy.
Flow Element Installation
Install the flow element in the process piping at the desired location. FCI recommends that the A side of the flow
element be placed so it is on the up-stream side of the normal flow direction. Verify that the flat area machined into
the flow element is flat, up and level. The flat is machined on the flow element near where it is screwed into the
enclosure. "FLAT UP & LEVEL" is also etched on the flat surface.
Threaded Mounting
Apply a lubricant/sealant compatible with the process to all threads. Use a pipe wrench for 1-1/4 inch (32mm) NPT
and larger connections (including exotic materials of construction), or an open-end wrench for 1-1/4 inch (32mm)
NPT and smaller connections. All connections should be tightened firmly. To avoid leaks, do not overtighten or
cross-thread connections. The figures in Appendix A and Figure 2-1, show this configuration.
