Using BaroMerge Software
BaroMerge Software is used to post-correct absolute (non-vented) level sensor data to eliminate barometric pressure effects
from the measurements. BaroMerge Software can be accessed through the Win-Situ 5 Software
Tools menu. BaroMerge
provides three options to correct data.
l
Fixed Correction —A single offset value is applied to all selected log data. Use this option if you know the
barometric pressure of the site during the log, and know that it did not change.
l
Manual Entry —Specify two or more correction values to apply to the log data. Use this option if you wish to
manually enter a data set of barometric pressure values.
l
BaroTROLL log file —Absolute level sensor data points are individually corrected to reflect barometric pressure
changes that were logged by a BaroTROLL instrument during the approximate time period.
BaroMerge Input—BaroTROLL File
Log files that contain absolute data can be barometrically compensated using values logged by the In-Situ Inc. BaroTROLL
Instrument. Select this method when you have access to a BaroTROLL log file covering approximately the same time period
as the data file you intend to correct.
To use this correction method, you need the name of the BaroTROLL log file and the name(s) of the absolute log file(s) you
want to correct.
