 Backward Bidirectional Choose this option when the
Surface Combo Sensor is installed facing downstream and
to ens ure the monit or ana lyzes flows moving bo th away
from and toward the face of the sensor. This option would
be beneficial, for example, when using a weir to measure
overflows with the pote ntial of river intrusion.
 Maximum Velocity Select the maximum expected velocity
that will occur at the site for the monitor to use in fine-tuning
the velocity data. The Auto option serves to optimize the range
and resolution of the velocity data samples to match the
characteristics of the flow. The default setting is 10 fps.
 Duration Select the amo unt of time for the sensor to transmit
and receive the velocity signal based o n the noise present at the
monitoring point. Most sites require only a one (1) second
(default) interval. However, sites that exp er ience elevated
noise levels or velocity dr o p outs to zero require a longer
interval (2).
 Coeffici ent A Enter the factor (offset) by which to calibrate
surface velocity to ensure accurate surface velocity readings
across all velocity ranges. ADS strongly recommends using the
default setting (0 fps) for this offset; therefore, please contact
ADS before modifying this setting.
 Coeffici ent B Enter the factor (gain) b y which to calculate
surface velocity to ensure accurate surface velocity readings
across all velocity ranges. ADS strongly recommends using the
default setting (1.00); therefore, please contact ADS before
modifying this setting.
 Gain This value repr esents the factor applied to raw velocity
(RAWVEL entity in Qstart) to determine average velocity and
to calculate quantity for the Flow 1(2) device. Qstart does not
apply the Gain to the velocity readings repor te d in Diagnostics,
where the raw velocity readings are used for comparison
against the manual measurements.
 Cross Check Gain Enter t he value by which to multiply raw
velocity readings in the monitor to deter mine average velocity
for comparison purposes in the monitor. The defau lt is 0.90.
