Leveloggers & Barologger 5: Accurate Water Level Monitoring
Intro: Best for precise water level compensation
Leveloggers measure absolute pressure (water pressure + atmospheric pressure) in feet, meters, centimeters, psi, kPa, or mbar. The Barologger 5 records atmospheric pressure only, allowing precise barometric compensation for multiple Leveloggers on site.
Applications
- Pump and slug tests
- Reservoir and stormwater runoff management
- Watershed and drainage basin monitoring
- Stream gauging, lake, and wetland monitoring
- Tank level measurement
- Monitoring water levels in wells and surface water
Important: The Barologger should not directly monitor water. It calculates compensation by recording air pressure, which is more accurate than water pressure for correcting Levelogger data.
Industry Advantages
Barologger 5 is widely used in hydrology, environmental monitoring, and civil engineering. Users value its reliability, simple deployment, and compatibility with Levelogger Edge, Gold, Junior, and older models. Its key advantage is allowing one Barologger to compensate all Leveloggers within a 30 km (20 miles) radius or 300 m (1000 ft.) elevation difference, streamlining large-scale monitoring.
Why Use a Barologger?
To accurately measure changes in water level, barometric pressure fluctuations must be removed from Levelogger data. Suspending a Barologger above the water allows it to record ambient fluctuations, which can then be automatically compensated using Levelogger Software. A single Barologger can cover a 30 km (20 mile) radius.
Manual Barometric Compensation
If an on-site Barologger is unavailable, local weather station data can be used. The station should be within 20 miles (30 km) and 1000 ft (300 m) elevation range. Align date, time, and units with Levelogger data. Older Levelogger models require offset adjustments; Levelogger Edge does not.
| Pressure Conversion Factors | ||
|---|---|---|
| Barometric Unit | FOOT Water Column Equivalent | METER Water Column Equivalent |
| 1 psi | 2.30666 | 0.703070 |
| 1 kPa | 0.334553 | 0.101972 |
| 1 mbar | 0.0334553 | 0.0101972 |
Example 1: 15 psi × 2.30666 ft/psi = 34.60 ft water head
Example 2: 101.40 kPa × 0.101972 m/kPa = 10.34 m - 9.50 m offset = 0.84 m head
* Green values denote pressure conversion factors; see table above for reference.
Subtract calculated barometric values from Levelogger data. For example, uncompensated Levelogger Edge reading 41.17 ft minus 34.60 ft = 6.57 ft compensated. Older Levelogger reading 3 m minus 0.84 m = 2.16 m compensated.
Barologger Installation
The Barologger monitors barometric fluctuations to correct Levelogger readings. It can compensate all Leveloggers within a 30 km (20 mile) radius or 300 m (1000 ft) elevation change. Never submerge the Barologger.
Install in a vented well above high water. Maintain similar thermal conditions to Leveloggers. For groundwater, suspend beyond frost line; for surface water, deploy in a dry well or float in a stilling well.
Q&A
Can one Barologger compensate multiple Leveloggers?
Yes, a single Barologger can compensate Leveloggers within 30 km (20 miles) or 300 m (1000 ft) elevation change.
Can I use Barologger to measure water directly?
No, Barologger measures air pressure to compensate Levelogger water readings; it is not designed for direct water monitoring.
What if I don’t have an on-site Barologger?
Use local weather station data within 30 km and 300 m elevation. Adjust offsets and units to match Levelogger data for accurate compensation.
