In the lower left portion of the Datalogger Settings tab is the area for setting channel parameters (level, temperature, conductivity, rainfall). The software will detect the available channels when the datalogger settings are retrieved.
184.108.40.206 Level Channel (Ch1)
Figure 5-2 Levelogger 5 Channel Setup
- 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.
- 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.
Readings can be converted to other units using the Data Wizard.
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.
There is no Offset input option for the Barologger
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.
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 -1000 ft below sea level and 16,400 ft (or -300 m and 5000 m) 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.
For other dataloggers, data can be adjusted for altitude and density post data collection using the Solinst Levelogger Software Data Wizard.
