Sensor Installation and Connection 3-33
 Surface Combo Sensor/Ultrasonic Depth Sensor
Physical Offset Measure the distance from the crown
(top) of the pipe to the face of the sensor (horizontal
surface with the two/four depth crystals to determine the
physical offset.
Note: These offsets are required when configuring the
monitor using the Profile or Qstart software.
11. Secure the sensor cables from the ring to the location at which
the monitor is mounted in the manhole. Refer to Securing the
Sensor Cables in the Pipe and Manhole on page 3-53 for more
information.
Special Installations
A special installation requires two independent installations: one
for the Surface Combo Sensor or Ultrasonic Depth Sensor and one
for the Peak Combo Sensor or Slimline Peak Combo Sensor.
Note: Special installations do not involve spreader
mechanisms or rings. All hardware mounts directly to the
pipe surface with anchor bolts.
Performing a special installation involves the following process:
 Gathering the parts and supplies
 Gathering the tools and equipment
 Mounting the Surface Combo Sensor or Ultrasonic Depth
Sensor
 Mounting the Peak Combo Sensor or Slimline Peak Combo
Sensor
 Securing the cables to the band
Before beginning the installation, conduct a thorough investigation
of hydraulic and other site conditions. The hydraulics of a site
directly affect the monitor's ability to accurately measure flow
