7. Hold the bracket firmly in place against the manhole wall.
8. Identify the three pre-drilled holes on the bottom of the
bracket, and spot drill the manhole wall through the middle
hole with a drill.
9. Rotate the bracket 90 , and drill and mount an M6 x 55-mm
anchor bolt.
10. Secure the bottom of the bracket with a washer and nut.
11. Slide the sensor into the mounting plate on the bracket, and
secure the cable with cable ties to keep the sensor in place.
12. Verify that the sensor portion of the bracket is level using a
carpenter’s level held to the face of the sensor. If it is slightly
out of level, make horizontal adjustments to the bottom portion
of the bracket by moving it to the left or right. The oval
bottom mounting holes allow minor horizontal adjustments.
13. Drill and mount an M6 x 55-mm anchor bolt in one of the
other pre-drilled holes at the top portion of the bracket for
extra security.
14. Confirm that the sensor is level.
15. Measure the physical offset for the sensor (the distance from
the crown (top) of the pipe to the face of the sensor). Enter
this distance as a negative value. For example, if it is 610 mm
(24 in) from the top of the pipe to the face of the sensor in the
manhole, you would enter -610 mm (-24 in) for the physical
offset.
Note: This value will be necessary when configuring the
monitor using the Profile or Qstart software.
