Process-wetted materials
Wetted material selection
Ensure that the process fluid is compatible with the
meter body wetted materials when specifying the
Rosemount 8800D Vortex Flowmeter. Corrosion will
shorten the life of the meter body. Because of the wide
variety of processes and applications, it is impossible to
guarantee material compatibility in a given process
without preforming corrosion tests under actual
operatiing conditions. Therefore, the final decision of
material selection resides with the end user.
Note
For accurate material identification, perform a
Positive Material Identification (PMI) test on a
machined surface.

Remote (optional)
Electronics may be mounted remote from the meter
body. Interconnecting coaxial cable available in
nonadjustable 10, 20, and 30 ft (3,0, 6,1, and 9,1 m)
lengths. Consult factory for non-standard lengths up to
75 ft (22,9 m). Remote mounting hardware includes a
polyurethane painted, carbon steel pipe mount bracket
with one carbon steel u-bolt.
Armored remote cables are also available in lengths of
10, 20, 33, 50 and 75 feet. The armored remote option
comes standard with an aluminum gland to connect
the cable to the meter and electronics. A stainless steel
gland is provided when ordered in conjunction with a
stainless steel electronics housing.
Temperature limitations for integral mounting
The maximum process temperature for integral mount
electronics is dependent on the ambient temperature
where the meter is installed. The electronics must not
exceed 185°F (85°C). The following is for reference,
please note that the pipe was insulated with 3 inches of
ceramic fiber insulator.
