Configuration and Activation 4-57
Note: When using an AV|Max or Peak Combo Sensor
and a Surface Combo Sensor at the same monitoring point,
ADS recommends maintaining the same settings for all of
the parameters corresponding to both Peak Velocity
(Velocity tab on the Edit Peak Combo Parameters
dialog) and Surcharge Peak Velocity (Peak Velocity tab in
the Edit Surface Combo Parameters dialog) to ensure
consistency between the velocity readings.
z Enable Select this checkbox to ensure the monitor begins
taking velocity readings at the designated interval once
activated. This option is selected by default.
z Store Data Select this checkbox to ensure the monitor logs
the velocity data to memory. 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 Sensitivity Select the appropriate velocity sensor sensitivity
from the drop-down list. A sensitivity that is too high may
produce noise, causing interference in the signal and resulting
in spikes in the data. A sensitivity that is too low can produce
readings that are low in comparison with confirmation
readings. The default sensitivity is 10.
z Velocity Direction Select one of the following options that
reflects the general direction of the flow at the monitoring
point and position of the velocity sensor. The default is
Forward.
Bidirectional Choose this option for monitoring points
that potentially experience reverse flows. The AV|Max
and Peak Combo Sensors typically are positioned facing
