Sensor Installation and Connection 3-49
 From the bottom of the adapter, use two M3 x 10mm
stainless steel flathead screws (do not substitute any other
screws) to secure the sensor to the adapter. The predrilled
screw holes in the adapter and in the bottom of the sensor
should be in alignment if the sensor is seated properly on
the adapter.
 Use two M3 x 10mm stainless steel flathead screws (do not
substitute any other screws) to secure the adapter to the
band at the appropriate location on the band to ensure the
sensor will be positioned between 15 and 45 degrees up
the side of the pipe (6:30 to 7:30 position) and below the
flow surface once installed. The nose of the sensor should
be facing the same direction as the upstream edge of the
band.
5. Secure the sensor cables along the downstream edge of the
band according to the instructions in Securing the Cables to the
Band on page 3-51.
6. Place the band in the pipe upstream at least 12 inchees (305
mm) [same distance as Surface Combo Sensor or Ultrasonic
Depth Sensor, when present] from the manhole invert. Position
the band on the left side of the pipe so that the sensors will
remain below the flow surface (during minimum flows) and
above the silt level.
7. Orient the band so that one of the pre-drilled anchor bolt holes
is just above the flow surface.
8. Spot drill the pipe wall through the hole, install a ¼-inch x 2 ¼-
inch (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.
