BaroTROLL® Instruments

BaroTROLL® and Rugged BaroTROLL® instruments offer reliable and accurate barometric pressure and temperature monitoring and logging. Use these instruments in conjunction with one or more Level TROLL® or Rugged TROLL® instruments to compensate for changes in water level due to barometric fluctuations. To automatically post correct data from a BaroTROLL® or Rugged BaroTROLL® instrument, use Win-Situ® Baro Merge™ software.
Applications:

Multi-step aquifer testing
Monitor barometric pressure and temperature
Conduct atmospheric research
Calculate barometric efficiency

BaroTROLL® Instrument

Built of titanium, the BaroTROLL® instrument accurately measures and logs barometric pressure and temperature. The 0.72-inch (1.83-cm) diameter housing contains highly precise sensors, data logger, and internal power. Use the BaroTROLL® instrument in conjunction with one or more non-vented (absolute) Level TROLL® instruments. Barometric readings are automatically subtracted from data collected by a Level TROLL® to compensate for changes in water level due to barometric fluctuations. The BaroTROLL® offers powerful, accurate and reliable barometric data collection.

Features:

Built-in Modbus/RS485, SDI-12, and 4-20 mA simplifies connection to SCADA and telemetry systems.
Low-power system guarantees long-term operation – a minimum of 5 years or 2 million readings.
Win-Situ® Baro Merge™ software automates post-correction of Level TROLL® data.
0.72-in (1.83-cm) diameter titanium housing is designed for harsh environments.

Rugged BaroTROLL®

Measure and log barometric pressure data with the affordable Rugged BaroTROLL® Instrument. The self-contained device compensates for changes in water level due to barometric fluctuations. Data from a Rugged BaroTROLL® can be automatically post-corrected by using Win-Situ® Baro Merge™ software. The Rugged BaroTROLL® can be used in conjunction with a Rugged TROLL® 100 or 200 instrument for optimum accuracy.

Features:

Use suspension wire (cable) with hanger for long-term deployments requiring minimal instrument access.
Use direct-read Rugged TROLL® cable when you need real-time access. The Rugged BaroTROLL® can be connected to a telemetry system, PLC system, or logger.
2.62-cm (1.03-in) diameter titanium housing is suitable for harsh environments
Extended battery life offers 5 years or 2 million readings
Can be used with a low-cost cable
