Drain Gauge - Passive Capillary Lysimeter
The Drain Gauge G2 & G3 provide accurate measurements of deep drainage and and contaminant fluxes at a low cost.
- Monitor groundwater leaching
- Close your water balance
- Measure Deep Percolation Accurately
Applications Include:
- Waste Landfill Sites. Used to identify drainage and monitor efficacy of cover systems.
- Food Processing Waste Sites. Maximizes applications by monitoring water drainage rates and water quality below the root zone.
- Environmental research. Measures percolation and recharge rates.
- Farming operations. Measures and informs irrigation during a cropping season.
- Golf Courses. Used to measure and control excess water applications and fertilizer losses.
Comparisons
| Technique | Accuracy | Spatial scale | Installation/ Maintenance | Cost | Comments |
| Pan lysimeter | Poor | Medium - Large | Low | $ | Flux divergence under unsaturated conditions |
| Static tension (wick) lysimeter (i.e. drain gauge) | Fair | Small - Medium | Low | $$ | Mid range accuracy, mid range cost |
| Controlled tension lysimeter | Excellent | Medium | High | $$$ | Minimal flux divergence/convergence issues. New turn-key systems with lower maintenance |
| Weighing lysimeter | Best | Medium | High | $$$$$ | Quantify and manipulate hydrology |

Drain Gauge G3
The new Drain Gauge G3 features a sealed design, allowing it to work in both saturated and unsaturated conditions. It also features a sampling reservoir 20 times larger than that of the Drain Gauge G2. » Learn more
Drain Gauge G2
The Drain Gauge G2 lets you measure drainage rates in unsaturated soils and collect soil water samples for chemical analysis to help assess potential groundwater contamination, measure percolation rates, and close your water balance. » Learn more
