 Tap the sensor mounting plate to the right or left with a
rubber mallet until it is level.
Warning: Tapping the mounting plate with the sensor
attached could damage the sensor. Always remove the
sensor before tapping the plate with a mallet.
 Reattach the sensor to the mounting plate, and recheck the
level.
7. Fully tighten the ring until it fits securely and completely flush
against the pipe wall.
Warning: Avoid over-tightening the ring. This could
bend the crank assembly.
8. Install an anchor bolt in the manhole wall just above the pipe
crown. Using an anchor cable tie, secure the Surface Combo
Sensor cable.
9. Restore any silt moved to its previous level, and confirm that
the Peak Combo Sensor is still above the silt level.
10. Measure the physical offsets for the sensors in the following
way.
 Peak Combo Sensor Physical Offset Manually
measure the depth of the flow from the bottom of the pipe
to the flow surface, and then measure the distance from the
nose (i.e., front end) of the Peak Combo Sensor to the flow
surface. Subtract the second measurement from the initial
depth of flow to determine the physical offset.
