Alignment of Flow Sensor
1 . Loosen the positioning collar set screws with a 3/32 inch Allen wrench . Place the alignment rod through the sight holes in
the flow sensor . See
Figure 2
. Using the alignment rod as a guide, align the flow sensor so the flow label arrow matches the
pipe flow direction and the alignment rod is exactly parallel to the pipe . This procedure aligns the impeller directly into the
fluid flow .

2 . As a backup to the flow arrow label, there is a small hole next to the larger sight hole of the upstream side . With a
3/32 inch Allen wrench, tighten the positioning collar set screws .
3 . Double check that the sight holes in the sleeve are parallel down the pipe and the flow arrow label matches the pipe liquid
flow direction .
4 . Cable routing: The positioning collar is threaded for connection of a standard 1/2 inch electrical conduit (flex cable) or a
wire strain relief . Route the cable as required . Be sure to leave enough flex in the cable or conduit to allow future removal
of the sensor for service or cleaning .
