Win-Situ Baro Merge can post-correct absolute (non-vented) level sensor
data to eliminate barometric pressure from the measurements. Or it can
be used with gauged (vented) level sensor data to calculate barometric
efficiency.
Baro Merge provides 3 options:
• Fixed Correction – A single offset value is applied to all selected log
data. Use this option if you know what the barometric pressure was
during the log, and it did not change
• Manual Entry – Specify 2 or more correction values to apply to the log
data. Use this option if you know that barometric pressure changed
during the log
• BaroTROLL log file – Absolute level sensor data are corrected by
barometric pressure values logged by an In-Situ BaroTROLL during the
same general time period
launching baro merge
Baro Merge may be launched as a stand-alone application from the
program group In-Situ Inc., or accessed from Win-Situ’s Tools menu when
both are installed on the same system.
input
In the Fixed Correction and Manual Entry options, it is important to know
the barometric pressure for the general time period covered by the log or
logs you want to correct.
Baro Merge uses a Wizard-like interface consisting of three main steps:
