Applications - deeper applications, higher fluctuations
- when barometric data is required (barometric efficiency)
- very humid conditions, risk of wellhead flooding
- areas prone to long-term freezing conditions
- hard to reach areas, cumbersome deployment
- shallow applications, low fluctuations
- surface water, wetlands
- watershed monitoring
- stormwater and flood monitoring
- no option for Barologger deployment, or don't want extra step of data compensation
