8. Spot drill the pipe wall through the hole, install a M6 x 55-mm
anchor bolt, and secure the band to the anchor bolt with a
washer and nut.
Note: Make sure the submerged portion of the band is
flush with the pipe wall. If it is not, remove the band and
conform the band to the pipe.
9. Install a M6 x 55-mm anchor bolt, washer, and nut below the
flow surface 30 to 80 mm away from the Peak Combo Sensor
or Slimline Peak Combo Sensor on each side. This will hold
the sensor securely against the pipe wall and prevent the end of
the band from twisting in the flow or catching debris.
10. Conform the portion of the band above the flow surface to the
pipe wall, and install an M6 x 55-mm anchor bolt, nut, and
washer every 305 to 610 mm up to the top of the band.

11. Measure the physical offset for the sensor by manually
measuring the depth of the flow from the bottom of the pipe to
the flow surface and then measuring the distance from the nose
(i.e., front end at the pipe surface) of the sensor to flow
surface. Subtract the second measurement from the initial
depth of flow to determine the physical offset.
