Rosemount Model 8800C Vortex Flowmeter with FOUNDATION
™
Fieldbus
2-10
High-Temperature Installations Install the meter body so the electronics are positioned to the side of or
below the pipe, as shown in Figure 2-1 on page 2-2. Insulation may be
required around the pipe to maintain a temperature below 185 °F
(85 °C).
Conduit Connections The electronics housing has two ports for
1
/2–14 NPT conduit
connections. Adapters are also available for PG 13.5 or M20ϫ1.5
conduit. These connections are made in a conventional manner in
accordance with local or plant electrical codes. Be sure to properly seal
unused ports to prevent moisture or other contamination from entering
the terminal block compartment of the electronics housing.
NOTE
In some applications it may be necessary to install conduit seals and
arrange for conduits to drain to prevent moisture from entering the
wiring compartment.
High-Point Installation Prevent condensation in any conduit from flowing into the housing by
mounting the flowmeter at a high point in the conduit run. If the
flowmeter is mounted at a low point in the conduit run, the terminal
compartment could fill with fluid.
If the conduit originates above the flowmeter, route conduit below the
flowmeter before entry. In some cases a drain seal may need to
be installed.

Cable Gland If you are using cable gland instead of conduit, follow the cable gland
manufacturer’s instructions for preparation and make the connections in a
conventional manner in accordance with local or plant electrical codes. Be
sure to properly seal unused ports to prevent moisture or other
contamination from entering the terminal block compartment of the
electronics housing.
