ADS Environmental Services FlowShark QR 775002 A4 - Manual (Page 141)

Configuration and Activation 6-15
 Blanking (auto) Select this checkbox to ensure the monitor
disregards depths occurring within a distance from the face of
the ultrasonic depth sensor equivalent to 5 percent of the range
from the sensor face to the bottom of the pipe. This (default)
setting effectively represents the vast majority of pipe/flow
conditions. Therefore, ADS strongly recommends selecting this
option for most applications.
 Blanking (override) Enter the distance from the face of the
ultrasonic depth sensor within which to ignore data potentially
representing erroneous readings. Use this option in place of the
auto-blanking option (above) to designate a distance greater
than 5 percent of the range from the face of the sensor to the
bottom of the pipe. Do not choose a distance shorter than 5
percent of the range. ADS recommends using this option only
when spikes in the data are occurring beyond the 5 percent
range and under direct consultation with an ADS
representative.
 Pipe Height This field represents the height of the pipe in
which the sensor is installed. This parameter is not editable
from this location.
