Manual
z Enable Select this checkbox to enable the parameters for
modification and 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 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 Paraflow
and Surface Combo Sensors typically are 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 ParaFlow and Surface Combo Sensor
typically are positioned facing upstream toward the
oncoming flow. This is the most common option for
selection. ADS recommends using this setting for most
monitoring applications.
Backward Choose this option for monitoring points at
which the ParaFlow or 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
