LevelTroll 700

LevelTroll700

Introducing the NEW Level TROLL ® 700 ... the next breakthrough for professional water level monitoring applications including single or multi-step aquifer testing, precision river gauging, tidal influence studies, wave characterization, geothermal research, storm-event monitoring and more!

The Level TROLL ® 700 features a rugged, all-titanium construction that is TIG welded to eliminate o-ring seals, Twist-Lock (TM) connectors, an ultra-low power system that eliminates the need to change batteries, and it is only 18.3mm (0.72 in) in diameter making it perfect for 1-inch wells or observation tubing. The 700 serie s of the Level TROLL ® offers new logging modes such as Linear , Linear Average , Event , True Logarithmic , Step Linear , and Fast Linear for complete customization. Additional benefits of the Level TROLL ® 700 include “Pause” and “Re-Start” logging features, a larger memory (350,000+ data points), 0.25 sec sampling (4 samples per second), ability to store and manage up to 50 log files, user notes, advanced compensation settings, and more.

The Level TROLL ® comes standard with RS-485 Modbus, SDI-12, and 4-20mA communication options. It can be operated using a PC or a RuggedReader ® handheld and it can easily be connected to a SCADA or other online systems.

True Logarithmic sampling is commonly used for aquifer testing (pumping and slug tests) to collect a large volume of early-time drawdown data while minimizing the amount of data collected later on. A convenient new “Re-Start” feature makes multi-step pumping tests easy. When changing the rate of the pump to the next step, simply press the “Re-Start” button and the logarithmic sampling rate will re-start at the beginning collecting a log cycle within the same file! A single log file can be restarted as many times as needed. Other modes such at “Step Log” and “Fast Linear” provide additional monitoring flexibility.

Applications:

Multi-step aquifer testing
Slug tests
Pumping tests
Tidal influence & wave characterization
River, lake, stream gauging
Landslide & flood prevention
Stormwater monitoring
Flow measurements
Research, studies
Marine buoys
Water pumping management
Estuaries and coastal monitoring

Features & Benefits:

Ultra-rugged, all-titanium design – Perfect for fresh and marine water monitoring. No more worries about corrosion. Excellent for marine, brackish and acidic sites.
Super accurate sensors – record minute changes in water level and temperature.
TIG-welded seals – Prevents flooding of instrument.
Ultra-low power system guarantees 5 years or 2-million data points – Forget changing batteries or running out of power.
Uses external battery or line power – no worries about running out of power.
RS-485 MODBUS, SDI-12, and 4-20mA – provides for easy connections to existing and online systems
Twist-Lock(TM) connectors that “lock” tight – 100% reliability
Halogen-free cables (LSZH rated) – no worries of toxic fumes if submitted to fire
Sealed desiccant options – allow for barometric compensation for maximum accuracy while preventing water & humidity intrusion
Extend cables by simply adding additional segments – maximizes your investment and maintain flexibility with your unit.
-20 to 80ºC temperature range – useful for geothermal and hot spring research and monitoring
Easiest ever Win-Situ ® software – get the data you need fast! Large, sizable display that's easy to see from a distance.
Linear logging – perfect for long-term monitoring
Pause logging feature – Pause logging when removing a unit. Reinstall and restart where you left off!
Specify start and stop times for logging – collect the data you need up to the date you want and no more
Ability to “undelete” files from the unit – no worries of accidentally deleting your data.
Data saved by sites not files – collect and save information by site automatically. No need to transfer data later.
Easy-to-read memory and battery gauges – know exactly how much is left
Friendly Wizards guide every step – reduces complicated steps and the need for tedious manuals
Submersible ranges up to 351m / cable length up to 1200m – measure to the depth you need.
FCC and CE emission tested – prevents susceptibility to outside emission interference and transient electrical surges
Version, range, and manufacturing info printed on side of the unit – know the details of the unit without opening the software. Reduces accidental over pressuring
