Configuration and Activation 6-17
 Max Velocity
Select the appropriate option from this drop-
down list to fine tune the maximum velocity value at the
selected monitoring point for greater accuracy in the velocity
data. An Auto option is available that allows the monitor to
dynamically modify the optimal maximum velocity based on
the current velocity readings to enhance the precision in
processing velocity data. It can read velocities up to 30 feet per
second (fps). However, ADS recommends using a fixed value
for monitoring points that typically remain dry, such as
overflows or sites downstream from pump stations. For these
applications, consider choosing the 10 or 15 fps option,
particularly where a sudden surge of flow traveling at more
than 3 fps can occur within a single interval.
 Sample Duration
Select the duration of time for the sensor
to fire based on the noise present at the location. This interval
should increase with elevated noise levels. ADS recommends
restricting the selected interval between 3 and 8 seconds.
 Flow Type
Select the option corresponding to the conditions
that generally reflect the monitoring point at which the Doppler
velocity sensor is installed.
 Typical
Choose this option for locations that consistently
experience continuous flow.
 Wet/Stagnant Choose this option for locations that
experience pooling, with only limited movement in the
flow.
 Usually Dry Choose this option for locations that are
characterized by an absence of flow, except during wet
weather conditions.
 Gain
This represents the factor that is applied to raw velocity
to determine average velocity when receiving diagnostic
readings and calculating quantity and typical days in the
monitor. This parameter is editable through the Quantity
Coefficient Generator
tool in Profile.
