WIRING
All electronic options are associated
with a matching style of meter
cover plate. This cover plate has
four threaded ports, compatible
with PG7 threads, for gaining wiring
access to the electronics inside the
cover plate. The meter is shipped
with the ports environmentally
sealed with a threaded plug and
seal. Remove one or more of
these plugs as required to install
the supplied port fittings below.
Each meter is supplied with cable
gland strain reliefs with O-rings and
1/2 NPT adapters with seals for use
in the threaded ports of the meter
cover plate. Select the port fittings
that fit your process and replace
the threaded plugs in the cover
plate with the fittings as required.
The threaded plugs installed at the
factory may be left in any unused
cover plate port indefinitely.
It is recommended that a
“removable” thread-locker (fluid,
stick, tape, spray, etc.) be used
when installing the strain reliefs or
adapters into the cover plate ports.
Strain Reliefs:
The cable gland strain reliefs will
accommodate a cable diameter of
0.11 - 0.26 inches (2.79 - 6.6mm)
and provide an environmental
seal around the cable when
the dome-nut is tightened.
NPT Adapters:
The 1/2 NPT adapter fittings
are used for attaching flex
conduit to the meter, for those
applications that require cable
runs to be enclosed in conduit.
• Cable to be provided by
customer to accommodate
job requirements. Cable is
not included with meter.
• This meter is externally
powered. The magnetic coils,
electrodes and other electronic
components within the main
meter body receive power from
the electronics housed within the
cover plate. All external wiring
connects to the cover plate
through threaded ports. See the
included electronics manuals for
meter wiring diagrams specific
to this meters electronics.
MAINTENANCE
The meter is virtually maintenance-
free. However, it is important
to keep the meter clean and
free of contaminants.
CAUTION:
Do not allow liquids
to dry inside the meter. The
electrodes may develop a film
that degrades accuracy.
Remove internal debris or deposits
using soft brush or small probe.
NOTE:
Make sure the arrow on the
meter is pointed in the direction
of fluid flow (see Figure 2).
