YSI Level Scout

The Level Scout instrument is designed to measure level and temperature accurately and record the readings (along with time stamp) at user-selectable rates. Internal batteries provide power and provide years of data logging capabilities. Data logging modes include linear, linear averaging, event triggered, and logarithmic sampling. The batteries are field-replaceable with a quick-disconnect cable assembly.

The Data Scout Advanced desktop software can be used to set up logging sequences, display tabular and graphical data, correlate barometric data, download logged data from multiple Level Scouts, acquire real-time data sampling, and configure alarms. In addition to the software, the instrument firmware can be upgraded in the field as new versions are released.

LevelTROLLs 100, 300, 500 and 700

In-Situ LevelTROLL®
Water Level Monitor and Loggers

The LevelTROLL® contains everything needed for water level measurement and datalogging – level and temperature sensors, a data logger, internal power and a lot of exciting new capabilities. Since it is built entirely from rugged titanium welded to eliminate O-ring seals, you can have total confidence in all applications, even marine environments. The LevelTROLL® is the easiest way to monitor water levels ever!

With the LevelTROLL®, you'll discover perfect connections with our new Twist-Lock™ connectors (patent pending) and RuggedCables®. And they are extendable – an industry first!

GUARANTEED BATTERY LIFE
Only industry guarantee for battery life – 5 years or 2 million readings or free instrument replacement!
SUPERIOR ACCURACY AND PERFORMANCE
In-Situ® uses the newest sensor technologies. All instruments undergo an extensive full-scale calibration procedure for both pressure and
temperature. A serialized calibration report comes with each instrument.
RUGGED AND RELIABLE
All LevelTROLL sensors are designed for use in many applications. Use 316 stainless steel (300) and titanium (500, 700) sensors in all types of environmental waters. For superior corrosion-resistance in brackish or saltwater, choose acetal alloy or titanium.
FLEXIBLE COMMUNICATIONS
The LevelTROLL 300, 500 and 700 instruments feature Modbus (RS485), SDI-12 and 4-20mA outputs. Connect each of these units to a SCADA or PLC system without any special adaptors.
INDUSTRY-LEADING WIN-SITU SOFTWARE
The communication platform used to set up, control and manage data from LevelTROLL® instruments. The software has been designed to be powerful and easy-to-use. Win-Situ 5 software is included with the purchase of LevelTROLL 300, 500 and 700 instruments.

In-Situ BaroTROLL®

The BaroTROLL® is a low-cost, self-contained logger that measures barometric pressure. It contains highly precise barometric and temperature sensors, a data logger, and internal power in a 18.3mm (0.72 in.) diameter housing. The low-powered system practically eliminates the need to change batteries and guarantees long-term operation. Alternatively, the unit can be powered with external power. System integration is a snap with built-in RS-485/232 Modbus, SDI-12, and
4-20mA communications.

The BaroTROLL® is typically used in conjunction with one or more of the non-vented Level TROLL instruments to compensate for changes in water level due to barometric fluctuations. Readings from the BaroTROLL can be automatically subtracted from data collected by a Level TROLL®.

Barometric pressure, temperature & data logging in a 18.3mm (0.72 in.) OD – Fits in a 25mm (1 in.) well.
Ultra-rugged, all-titanium design – Perfect for corrosive sites.
TIG-welded seals – Prevents flooding of instrument.
Ultra-low power system guarantees 5 years or 2 million readings – Forget about changing batteries or running out of power.
Uses external battery or line power – Never run out of power.
Sealed Twist-Lock hanger – 100% reliability
Easy-to-use Win-Situ® software – Get the data you need fast! Large, sizable display that's easy to see from a distance.
Extremely accurate sensors – Record minute changes in barometric pressure and temperature.
Modbus, SDI-12, and 4-20mA – Provides for easy connections to existing and online systems.
