and snap into place. Each end
of a half-ring has a small lobe
that snaps into a recess at the
top and bottom of the groove for
retention. Repeat at other end.
Customer to provide:
• Ring Gaskets or Full-Face
Gaskets approved for use with
type flange installed (ANSI
or DIN) and the fluid being
monitored (2 required).
• 5/8 in. bolts and nuts for
ANSI flanges. Four per side
for 3-inch meters; eight per
side for 4-inch meters.
• 16mm bolts and nuts for DIN
flanges. Four per side for 3”
meters (DN80/PN10 flanges);
Eight per side for 4” meters
(DN100/PN10 flanges).
• Torque bolts using a star
pattern to 25 ft-lbs (33.9 N•m).
For best results, always verify
torque accuracy before use.
NOTE:
Do not over tighten the
flange bolts. This may cause the
gasket to be compressed into the
flow stream and may decrease
the accuracy of the meter.
When properly installed, the flow
meter will only measure flow in that
portion of the piping system where
the meter is installed. Choose the
location with the longest straight
unobstructed run of pipe, keeping
in mind that in some applications it
may be possible to locate the meter
in either the supply or return pipe.
NOTE:
Your meter may have two
1/8 in. NPT pipe plugs installed on
top of the flow tube near each end.
They have been installed and sealed
at the factory and are for use only
with optional temperature sensing
probes for energy use calculations
in specialized applications.
RECOMMENDED INSTALLATION
WARNING:
Compatibility of
this product’s material and the
process fluid and/or environment
should be considered prior
to putting into service.
WARNING:
Product should
never be operated outside its
published specifications for
temperature or pressure. See
specifications for your model.
WARNING:
Make sure flow and
pressure have been eliminated
from process pipe prior to
installing or removing product.
WARNING:
When connecting
product to process piping: For
NPT fittings use non-lubricated
thread sealant (such as Loctite®
No More Leaks™ Plastic Pipe
Thread Sealant or NSF equivalent
for NSF applications). For BSPP
fittings use O-ring seals. For flange
fittings use flange gaskets.
CAUTION:
Installation near
high electromagnetic fields
and high current fields is not
recommended and may result
in inaccurate readings.
CAUTION:
Do not allow water
to freeze in meter. Ice expansion
may burst the plastic housing.
CAUTION:
Do not allow this
meter to be used with steam.
CAUTION:
Using metal fittings on
the plastic threaded pipe ends of
the meter is not recommended.
