Configuration and Activation 4-51
z Pipe Height This field displays the pipe height at the
monitoring point, based on the installation table. This
parameter is not editable from this location.
Note: Under normal conditions, the remaining
parameters corresponding to the AV|Max or Peak Combo
device should not require modification. However, if
additional adjustments are necessary, the following
sections provide a detailed description of each parameter.
Ultrasonic tab – AV|Max or Peak Combo
Edit the following parameters corresponding to the upward-looking
ultrasonic depth sensor in the AV|Max or Peak Combo Sensor:
z Enable Select this checkbox to ensure the monitor begins
taking upward ultrasonic depth readings at the designated
interval upon activation. This option is selected by default.
z Flow Type Select the option that best reflects the kind of
flow conditions that typically occur at the monitoring point
from the drop-down list:
Typical Flow exhibits a typical diurnal pattern. This is
the default setting.
Wet/Stagnant Flow remains in the pipe but moves only
during wet weather events.
Usually Dry Pipe typically remains dry, except under
wet weather conditions.
z Electronic Offset Enter the difference that exists between
the depth sensor readings and the manually measured depth.
The default value is 0.
z Deadband Select the distance from the sensor face within
which readings received will be ignored. The default value
(Auto) represents a percentage of the flow depth and should be
sufficient under normal circumstances. It also is the best
option for handling shallow flows. However, consider another
value when the sensor readings reveal a potential problem with
false dropouts. Choose a value for the deadband that is
sufficiently below the minimum depths that legitimately occur
