Caution
Do not connect the powered signal wiring to the test terminals. Power could damage the test
diode in the test connection. Twisted pairs are required to minimize noise pick up in the 4 - 20 mA
signal and digital communication signal. For high EMI/RFI environments, shielded signal wire is
required and preferred in all other installations. Use 24 AWG or larger wire and do not exceed
5,000 feet (1,500 meters). For F
installations for maximum performance. For ambient temperatures above 140 °F (60 °C) use wire
rated to 176 °F (90 °C).
Figure 14 shows wiring connections necessary to power a Rosemount 8800D and
enable communications with a hand-held Field Communicator.

OUNDATION
4. Plug and seal unused conduit connections. Use pipe sealing tape or paste on
threads to ensure a moisture-tight seal. Housing conduit entries marked with
M20 will require M-20 x 1.5 blanking plug thread. Unmarked conduit entries
will require a
Note
Straight threads require a minimum of three (3) wraps of tape to obtain a tight seal.
5. If applicable, install wiring with a drip loop. Arrange the drip loop so the
bottom is lower than the conduit connections and the flowmeter housing.
Rosemount 8800D Vortex units ordered with painted meter body may be subject
to electrostatic discharge. To avoid electrostatic charge build-up, do not rub the
meter body with a dry cloth or clean with solvents.
