• Enable Select this checkbox to ensure the monitor begins
taking velocity readings at the designated interval once
activated and to enable the parameter fields for editing.
• Flow Type Select option that most accurately reflects the
kind of flow conditions that typically occur at the monitoring
point.
 Typical Flow exhibits a typical diurnal pattern.
 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.
• 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 manual confirmation
readings. This value should only by changed on the advice of
trained ADS personnel.
• 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.
 Bidirectional Choose this option for monitoring points
that may experience reverse flows. The Peak Combo
Sensor is typically positioned facing upstream into the
flow. Choosing this ensures the monitor analyzes both
positive and negative values returned from the velocity
sensor.
 Forward Choose this option for monitoring points where
reverse flows are not expected and to ensure the monitor
only analyzes positive values returned from the velocity
sensor. The Peak Velocity Sensor is typically positioned
facing upstream into the flow. ADS recommends using this
setting for most applications.
