Sensor Installation and Connection 5-49
12. Install ¼-inch x 2 ¼-inch (M6 x 55-mm) anchor bolts, nuts and
washers at the pre-drilled hole at the short end of the band and
at the pre-drilled holes along the long end of the band (above
the flow surface) approximately every 12 to 24 inches (305 to
610 mm) to the top end of the band.
13. 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 the flow
surface. Subtract the second measurement from the initial
depth of flow to determine the physical offset.
14. Run the sensor cables from the sensor location in the pipe to
the monitor location in the manhole according to the
instructions in on page 5-80.
½-Band Mount
Perform the following procedure to mount an AV|Gated, AV|Max
or Peak Combo sensor in a pipe using the ½-band mount:
1. Use a hacksaw to cut the band to the appropriate length. Cut
the band so that, once installed, it will run almost completely
down the left side of the pipe.
2. Determine the best location on the band to mount the sensor.
Intend on installing the band on the left side of the incoming
pipe (upstream from the manhaole) to accommodate the sensor
cable and a Silt Mount Adapter. The sensor should mount as
close as possible to the bottom (end) of the band, making sure
the sensor will be both
above the silt level and below the flow
surface once installed.
Note: Mounting the AV|Gated, AV|Max or Peak Combo
Sensor between 5 and 30 degrees up the side of the pipe
from the centerline requires a special
Silt Mount Adapter .
3. ( applies only when mounting the AV|Gated, AV|Max, or Peak
Combo sensor /- 5 degrees of the 6:00 position. )
Mount the sensor onto the inside of the band with two M3 x
10-mm countersink screws, making sure the blunt end (i.e.,
nose) of the sensor is facing the upstream edge of the ring
