Water Level Sensors

Van Essen



The Baro-Diver is an atmospheric datalogger designed to increase the accuracy of long-term uninterrupted, real time water level monitoring.

Manufactured from 316L Stainless Steel and measuring just 22mm in diameter, the Baro-Diver incorporates an internal pressure sensor that measures the equivalent of hydrostatic pressure (above water) used in the calculation of total water depth.

Baro-Diver is ideal for various applications including:

• Barometric compensation
• Groundwater monitoring projects
• Surface water monitoring
• Monitoring of shallow waters
• Estuary and wetlands monitoring
• Aquifer storage and recovery


Baro-Diver Datlogging Capacity

The Baro-Diver can store an impressive 72,000 data-points including:

• Date
• Time
• Depth
• Pressure
• Temperature
