5.1.1 Setting Up Channel Information
In the lower left portion of the Datalogger Settings tab is the area for setting channel parameters
(level, temperature, conductivity, rainfall). The Levelogger Software will detect the available channels when
the datalogger settings are retrieved.
5.1.1.1 Level Channel (Ch1)
• Identification
describes the measurement parameter of the channel and has already been configured
as ‘LEVEL’. The channel can be re-named to suit each project. The channel
monitors water
column equivalent pressure
. The Identification field will be the channel heading, data column
heading and graph line name when viewing the data. Identification is limited to 32 characters.
• Unit
refers to the channel’s unit of measurement (m is default). See Table 5-1 for options.
Note:
Readings can be converted to other units using the Data Wizard.
Note:
If you set your Levelogger to record in pressure units (kPa, bar, psi), you can not change the offset or
enter an elevation value (in the Data Wizard). Only raw pressure readings will be provided.
•
Offset
refers to an adjustment, such as the distance between the tip of the Levelogger and the
monitoring well cap or static water level. It is recommended that the value of 0.00 be used, as this
keeps all subsequent readings relative to the tip of the Levelogger. The reference range is -300 m to
5000 m or -1000 to 16,400 ft.
Note:
There is no Offset input option for the Barologger.
Note:
Readings can be corrected or offset with respect to a specific reference elevation or datum for a much
wider spectrum of numeric offsets as part of the Data Wizard.
Figure 5-2 Levelogger 5 Channel Setup
The Levelogger Gold, Levelogger Junior, and LTC Levelogger Junior also have inputs for:
• Altitude
in feet or meters above sea level, at which the logger is actually deployed, is input in the
altitude field. You can enter an elevation between -300 m below sea level and 5000 m (or -1000 ft
and 16,400 ft) above sea level. The readings will then be automatically compensated for elevation.
•
Density
is used to adjust the range of the Levelogger based on the sample fluid density. The range
for the density adjustment is from 0.9 kg/L to 1.1 kg/L.
Note:
For other dataloggers, data can be adjusted for altitude and density post data collection using the
Solinst Levelogger Software Data Wizard.
5.1.1.2 Temperature Channel (Ch2)
• Identification
describes the measurement parameter of the channel and has already been configured
as 'TEMPERATURE’. The channel can be re-named to suit each project. The Identification field will
be the channel heading, data column heading and graph line name when viewing the data.
Identification is limited to 32 characters.
• Unit
refers to the channel’s unit of measurement. For the Levelogger and Barologger, the temperature
channel can be set to °C (default) or ºF (except Gold Series dataloggers).
