10. Secure the bottom of the bracket with a washer and nut.
11. Slide the sensor into the bracket, and secure the sensor with
cable ties to keep the sensor in place.
12. Verify that the sensor portion of the bracket is level using the
24-inch 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 a ¼-inch x 2 ¼-inch anchor bolt in one of the
other pre-drilled holes at the top portion of the bracket for
added security.
14. Confirm that the sensor is level.
15. Measure the physical offset for the ultrasonic depth sensor (the
distance from the crown (top) of the pipe to the face of the
sensor). Enter this distance as negative value when editing the
parameters for the Ultrasonic Device in Profile. For example,
if it is 24 inches (610 mm) from the top of the pipe to the face
of the sensor in the manhole, the physical offset would be -24
inches.
Note:
This value will be necessary when configuring the
monitor using the Profile software.
Mounting the Doppler Velocity and Pressure Depth
Sensors
Two special installation methods are available for mounting the
Doppler velocity and pressure depth sensors:

¾-band mount

½-band mount
Both mounts require almost identical installation methods. The only
significant differences are that the ¾-band mount allows the
installer to secure the band to both sides of the pipe wall and to
position the Doppler velocity sensor at the bottom center of the
pipe. These options are not possible using the ½-band mount.
