Superseded Models
This system supercedes the previous UNIDATA Model 6529-1 instrument.
1.3
Automating Existing Evaporation Pans
The evaporation instrument system and optional weather instruments can be
added to any evaporation pan installation. Contact your nearest UNIDATA
support office for advice on upgrades.
1.4
Logging Evaporation
A special instrument and scheme have been created within the UNIDATA
software to monitor the recorded water level, extract the evaporation and
rainfall data, and reset the pan water level. These have been included with
STARLOG v3.09E (or later) and are supplied on disk with initial releases of
the instrument. Alternatively, you can obtain this update from the technical
support section on the UNIDATA web site - www.unidata.com.au. Refer to
Software Requirements on page 31 for details on how to install the update.
This scheme offers you the options to log the raw water level, total
evaporation and total rainfall. You can log either one daily total or
measurements throughout each day. The evaporation data accumulates all
0.2mm water level falls, and the rainfall data all 0.2mm rises. The effects of
any pan water level resets and minor water level pulsations are not recorded.
