
Transmit Frequency
Select the frequency at which to
transmit the signal. ADS recommends leaving the default
setting (
Normal ) for most applications. However, if hydraulic
conditions at the site are resulting in questionable or erroneous
readings, consider applying one of the other frequency options.
Contact ADS for assistance when necessary.

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 12.

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 Surface
Combo Sensor typically is positioned facing upstream
toward the oncoming 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 Surface Combo Sensor typically is positioned
facing upstream toward the oncoming flow. This is the
most common option for selection. ADS recommends
using this setting for most monitoring applications. It also
requires less processing time and conserves power.

Backward Choose this option for monitoring points at
which the Surface Combo Sensor has been positioned
facing downstream and to ensure the monitor only analyzes
flows moving
away from the face of the sensor. One
application in which this would be the preferable option
would be for measuring velocity in an outgoing line
following two incoming lines in the manhole.
