After removing the flowtube from its shipping carton, inspect it for
visible damage. If any damage is observed, notify the carrier imme-
diately and request an inspection report. Obtain a signed copy of the
report form the carrier. The calibration certificate and any other docu-
mentation shipped with the VFM 3100 should be separated from the
packing material and held for future reference. Re-install any flange
covers or protective material to safeguard the VFM 3100 until it is in-
stalled.
Packing material should be disposed of in accordance with local
regulations. All packing material is non-hazardous and is generally
acceptable to landfills.
1.1.6. VFM 3100 Identification
The model code is stamped on the data plate as shown in Figure 3
and is digitally readable from the configuration menu.
The Standard Temperature Range sensor is made of 316 stainless
steel and is filled with silicone oil, maximum temperature 200 °C
(400 °F). An optional fill is Fluorolube, maximum temperature 90 °C
(200 °F). The Extended Temperature Range sensor is made of 316
stainless steel and is unfilled, maximum temperature 430 °C (800 °F).
Both standard and high temperature sensors are available made
from Hastelloy.

cal safety descriptions listed in the table above. For detailed infor-
mation or status of testing laboratory approvals/ certifications,

1.1.5. Unpacking
The VFM 3100 is built to be durable, but it is part of a calibrated
precision system and should be handled as such.
NOTE: VFM 3100 may (depending on pressure rating of flanges
with which they will be used) have a set of centering spacers inclu-
ded. Do not discard these centering spacers. They must be used
to install the VFM 3100 properly.
VFM 3100 with remote-mounted electronics are rugged two-piece
units. A remote cable connection is assembled to the VFM 3100
junction box and electronics housing. The cable may be cut to the
required length per instructions beginning on page 13. Do not allow
the weight of either the flowtube or electronics housing to be sup-
ported by the remote cable.
Remove the flowtube from the shipping carton using care to avoid
dropping or otherwise subjecting it to impact, particularly at the
flange or wafer faces. Never put anything through the flowtube for
lifting purposes as damage to the shedder bar may occur.
