3001 Barologger 6

Barometric pressure and temperature datalogger used to compensate Levelogger water level data.

Air pressure measurement in psi, kPa or mbar with ±0.05 kPa accuracy
Pressure algorithms based on air rather than water pressure for superior accuracy
150,000 data sets of memory plus a dedicated 20,000-reading backup, with a 10-year battery

Quantity

Overview

The Barologger 6 records atmospheric pressure and temperature on site. Set above high water level in one location, it is used to compensate Levelogger data for atmospheric pressure fluctuations, avoiding time lag in the compensation.

Typical applications

Barometric compensation of Levelogger 6, 5, Edge and Junior data
Site-wide barometric compensation: one Barologger compensates all Leveloggers within a 30 km (20 mile) radius and/or with every 300 m (1000 ft) change in elevation
Determining barometric lag and/or barometric efficiency of the monitored aquifer

Key Features

Records atmospheric pressure in psi, kPa or mbar, plus temperature in °C or °F
±0.05 kPa accuracy with 0.002% FS resolution
Pressure algorithms based on air rather than water pressure
Backwards compatible: Levelogger Software recognizes the Levelogger type and compensates using the same units as the submerged data file
150,000 sets of readings with a dedicated 20,000-reading backup memory
10-year battery life (based on 1 reading/minute)
Linear, event and user-selectable sampling with repeat mode, future start, future stop and real-time view
Measurement rates from 1/8 second to 99 hours

Benefits

No Time Lag: compensating with a Barologger 6 is the most accurate method of obtaining changes in water level, avoiding time lag in the compensation.
Site-Wide Coverage: one Barologger can compensate all Leveloggers within a 30 km (20 mile) radius and/or with every 300 m (1000 ft) change in elevation.
Automatic Compensation: the Levelogger Software Data Wizard automatically produces compensated data files using synchronized data files from the Barologger and Leveloggers on site.
Superior Accuracy: the Barologger 6 uses pressure algorithms based on air rather than water pressure.
Backwards Compatible: works with submerged Levelogger 6, 5, Edge and Junior data.
Aquifer Insight: the recorded barometric information can help determine barometric lag and/or barometric efficiency of the monitored aquifer.
