Installation Notes:
Once the adapter ends are installed on the upstream and downstream pipes, the meter is installed by tightening the collar nuts onto the inlet and outlet of the meter. These "true-union" fittings then allow the meter to be easily rotated to the proper orientation (face up), or removed for cleaning, repair, or replacement.
IMPORTANT!
These meter threads look practically identical to the NPT adapter threads BUT THEY ARE NOT!
Trying to install the meter without the adapter will damage the pipe's threads, the meter's threads, or BOTH!
