2-5 Transit Precautions

2-6 Process Fluid Connections

To safeguard against damage during transit, transport the instrument to the
installation site in the same container used for transportation from the
factory if circumstances permit.
Prior to installation:
A. Verify that tubing fittings or tube size match the type and size supplied
with your SFP instrument. For flare tube connections, utilize the nut
provided with the instrument to assure compatibility with the male
threads on the transmitter.
B. Make certain that all piping and fittings are clean and free from obstruc-
tions.
C. Assure that the piping installation permits easy access to the instru-
ment.
Make sure that the orientation of the device allows for self-draining if
required and that any gas bubbles or liquid cannot be entrained in the
device. See Section 2-8 concerning mounting orientation.
Welded Tube Fittings
An instrument that comes with butt tube process connections may be
welded into process tubing using the instructions and procedures for PFA
tubing provided with the butt tubing welding equipment.
Flare Connections
When attaching a flared tube to the SFP, the nut supplied with the
instrument is put over the tube, the tube is heated, flared (using the
appropriate tool) and cooled. The flared tube is then pushed over the SFP
fitting until it reaches the nominal tube diameter. The amount of torque
required to tighten the nut depends on the fitting size. See Table 2-1.

Torque Min (inch lbs)
Torque Max (inch.lbs)
Care should be taken to avoid applying excessive torque on the fitting,
which can result in irreparable damage to the fitting and to the device.
