Detection function when processing smart depth data. For
locations that typically do not experience surcharges,
disabling Surcharge Detection eliminates the processing
time required for this function and, as a result, conserves
monitor power.
Surface Velocity tab Surface Combo Device
• Enable Select this checkbox to ensure the monitor begins
taking velocity readings at the designated interval once
activated.
• 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 the other frequency option.
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 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 Surface 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 Surface Combo Sensor is typically positioned
