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 finger tighten
compression nut.
•
Install the adapter in the pipe fitting, using a thread
sealant.
