• 5/32” allen wrench
• Crescent Wrench
Optional:
• Channel locks
Warnings
• This meter is sensitive to heat. Do not weld or ame cut within
10’ of meter. Heat will damage electronics. (Heat will void
warranty.)
• Never attempt to remove a ow sensor when there is pressure
in the pipe unless it is specically designed for hot tap
installation and removal. Loosen the compression nut slowly
to release any trapped pressure. If uid sprays out when
removing the sensor, stop turning and depressurize the pipe.
Failure to do so could result in the sensor being thrown from
the pipe, resulting in damage or serious injury.
• Improper sealing of cables or cable glands will void warranty.
• Not recommended for installation downstream of a boiler
feedwater pump where installation fault may expose the
ow sensor to boiler pressure and temperature. Maximum
recommended temperature is 130°F (Plastic), 200°F (Metal).
• The EX11x/21x has a strong start and run current. When
using solar panels and VRSLA batteries as a power source, use
caution to insure the EX-Series sensor has the -50 Low-power
Option and that all Seametrics products on the power circuit
receive sufcient voltage and current under all conditions.
Failure to do so will lead to unreliable operation and possible
damage to the unit(s).
Refer to instruction manual for further details.

Installation
Fitting Installation
• Cut hole in pipe at desired location—recommended
size is 1 3/4”.
• Measure and write down the wall thickness.
• Strap saddle on pipe or weld the weldolet to the
pipe, aligning over hole.
Determine Proper Depth and K-Factor
• Run the K-factor Calculator, located at the bottom of
the seametrics.com web site to obtain Depth Setting
“D” and the K-factor.
Meter Installation
• Loosen compression nut so adapter shaft slides
freely. Pull meter fully upward and nger tighten
compression nut.
• Install the adapter in the pipe tting, using a thread
sealant.
Positioning & Grounding
Choose a position that will ensure a full pipe. Choose a position that will minimize ow distortion.

Connect grounding wire from
one of the housing screws or the
shaft of meter to a good earth
ground. If the pipe is metal, also
connect the grounding wire to a
grounding clamp on the pipe.

• Reinstall the sensor unit, being sure ow is in the
direction of the arrow on the housing.
• Loosen compression nut and lower meter to
appropriate depth “D”, which was obtained using
the K-factor calculator.
• Fully tighten compression nut.
