INSTALLATION (CONTINUED)
Provide a straight pipe run of at least 10Xs the pipe’s diameter upstream of
the meter, and at least 5Xs the pipe’s diameter downstream of the meter.
The arrow embossed on the insert body denotes the flow direction.

NOTE: There is no need to remove the insert to install the meter. The meter
must be installed with the arrow on the insert pointing in the flow direction.
If the meter is accidentally installed backwards, simply remove the insert,
rotate 180 degrees so the arrow points in the flow direction, and reinstall the
insert.
The Tee is bidirectional, the insert is not. The insert operates correctly as
long as the insert arrow is pointed in the direction of flow. The insert can be
rotated 180 degrees, so its arrow can always be pointed in the direction of
flow regardless of Tee installation.
If space allows, install Tee / insert at an angle rather than pointing up
(see Figure 3).
NOTE: For 1 inch pipe installations, this angle is especially important and
should be set at 45 degrees for most accurate meter operation.
