Certification
See the Declarations of conformity at end of this manual.
Unpacking and Inspection
Your instrument was carefully inspected before shipping. Check for any physical damage sustained during shipment. Notify
In-Situ and file a claim with the carriers involved if there is any shipping damage. Accessories may be shipped separately and

BaroTROLL Instrument
The titanium BaroTROLL measures and logs barometric pressure and temperature. Use the BaroTROLL in conjunction with
non-vented In-Situ Instruments.
Win-Situ BaroMerge Software simplifies post-correction of water level data by automatically subtracting barometric readings
from data collected by a non-vented instrument to compensate for changes in pressure due to barometric fluctuations.

About the Pressure/Level Sensor
A pressure transducer senses changes in pressure, measured in force per square unit of surface area, exerted by water or
other fluid on an internal media-isolated strain gauge. In-Situ offers instruments with either absolute (non-vented) or gauged
(vented) pressure sensors.
The "Absolute vs. Gauged: Comparing Absolute and Gauged Pressure Sensors" technical
note describes the difference between absolute and gauged pressure sensors and explains
the proper use of each type of sensor in different applications.
Absolute Pressure Sensor
An absolute or non-vented pressure sensor measures all pressure forces detected by the strain gauge, including atmospheric
pressure (PATM). The unit of measure is PSIA (pounds per square inch absolute), measured with respect to zero pressure.
The back of an absolute pressure sensor is sealed from the atmosphere. Therefore, the front of the absolute pressure sensor
responds to both atmospheric pressure and the pressure head of water above the sensor.
Absolute Sensor
1 Sensor back
2 Sensor front
3 Water pressure, PW(e.g., 20 PSI)
4 Atmospheric pressure PATM (e.g., 14.5 PSI)
5 Vacuum
Gauged Pressure Sensor
A gauged or vented pressure sensor eliminates the effects of atmospheric pressure because the vent tube in the cable allows
atmospheric pressure to be applied to the back of the sensor. The unit of measure is PSIG (pounds per square inch gauge),
measured with respect to atmospheric pressure.

1-800-446-7488 16 www.in-situ.com
Gauged Pressure Sensor
1 Sensor back
2 Sensor front
3 Water pressure, PW(e.g., 20 PSI)
4 Atmospheric pressure PATM (e.g., 14.5 PSI)
5 Atmospheric pressure PATM (e.g., 14.5 PSI)
BaroTROLL Atmospheric Pressure Sensor
Barometric pressure applies a direct stress upon open wells and surface water. Locally, barometric effects can change
significantly from location to location as a result of topographical and micro-meteorological changes. Therefore, it is important
to compensate for the barometric pressure changes when monitoring water elevation.

4 Vacuum
Configuring Depth and Level for PLC or Data Logger
When you configure level using the Sensors tab, the settings are stored in the instrument and are available for use in
Modbus, SDI-12, or 4-20 mA analog communication. A different configuration can be selected when you set up a log.

1-800-446-7488 17 www.in-situ.com
1. Connect the instrument to the software.
2. Click the Sensors tab .
3. Select the level/pressure sensor and click the Configure button. The Sensor Setup window appears.
4. In the Sensor Setup window, select the Level parameter, then click Configure The Level Setup Wizard opens.
5. In the Level Setup Wizard, select the options you want. For more information, view the Help in the Win-Situ 5
Software.

1-800-446-7488 18 www.in-situ.com
System Components
Instrument
The Level TROLL Instrument is completely sealed and contains no user-serviceable parts. The instrument includes pressure
and temperature sensors, a real-time clock, microprocessor, sealed lithium battery, data logger, and memory. Options
include a vented or non-vented pressure sensor in a variety of ranges.
RuggedCable System
RuggedCable Systems are custom-built, durable, direct-read cables that include the following items.
lTitanium twist-lock connectors for quick, reliable connections to the instrument, desiccant, and communication
cable
lMetal shield beneath the cable jacket to prevent electrical interferences
lKellems grip for secure instrument deployment
lSmall desiccant for vented systems (for storage only)
Non-vented cables are marked with VF, which means vent free.
Vented or Non-Vented Cable
Vented cable is used with vented pressure sensors to produce gauged measurements. The cable vent tube ensures that
atmospheric pressure is applied to the back of the sensor diaphragm.
Non-vented cable is used with non-vented instruments for absolute measurements. Compensate absolute measurements by
using a BaroTROLL Instrument and Win-Situ Baro Merge Software.
Vented cable is shipped with a small desiccant to protect against condensation. Larger
desiccants are necessary for deployment.
Jacket Options
Tefzel (vented) or thermoplastic polyurethane (TPU, vented or non-vented)
Customizable Cable Lengths
Cables can be ordered up to 1,219 m (4,000 ft).
Cable Termination
Cables can be ordered with a twist-lock termination (female connector) on both ends that connect to the instrument, the
TROLL Com Communication Device, desiccant, and other accessories.
Cables can also be ordered with stripped-and-tinned termination for wiring to a data logger or controller using SDI-12, analog
(4-20 mA), or Modbus communication protocol.

Suspension Wire
Polyurethane-coated stainless steel suspension cable can be used to deploy instruments with non-vented pressure sensors
such as the Level TROLL 400 Instrument, the non-vented Level TROLL 700 Instrument, and the BaroTROLL Instrument.
Suspension wire is appropriate to use when direct communication with the instrument is not necessary during deployment.
