In-Situ LevelTROLL 500

Level Troll 500

Applications:

  • River, lake & stream gauging
  • Long-term ground water monitoring
  • Water resource management, dams
  • Estuaries and coastal monitoring
  • Tidal influence & wave characterization
  • Landfill & industrial water levels
  • Water pumping management
  • Combined sewer overflow
  • Landslide & flood prevention
  • Marine buoys
  • Mine sites

In-Situ's mid-range offering in the LevelTROLL family of products, the LevelTROLL 500 contains all the advanced features of the 300-series unit but adds an all-titanium housing for added durability and corrosion resistance. Because of this, the 500 is ideal for deployment in brackish, marine and other harsh environments.

The LevelTROLL 500 is versatile performer built for long life and accurate logging in a number of different applications. Potential uses for the 500 include river, lake and stream gauging, long-term groundwater monitoring, tidal influence and wave characterization studies and more. With 1 MB of storage for up to 100,000 data points, and several options for easy connectivity with on- and off-line systems, the LevelTROLL 500 makes logging water levels and temperature simple.

Features and Specifications

  • Powerful sensors are among the most accurate in the industry.
  • Ultra-thin, 0.83mm OD design is easily deployed in narrow-diameter wells, boreholes and tubing.
  • TIG-welded seals and In-Situ's proprietary Twist-Lock™ cable connectors lock tight and prevent flooding for 100% reliability.
  • Ultra-low power system provides up to 5 years of guaranteed operations; the unit can also be powered externally for extra security.
  • Included Win-Situ software automates data collection and contains sophisticated graphing and analysis capabilities.
  • Advanced logging features including a pause function that allows the device to be removed and reinstalled without compromising data collection.
  • Smart save function automatically stores data by site.
  • "Undelete" feature prevents accidental data loss.
  • Segmented cables are extendable for deployment in depths up to 1200m.
  • Automatic post-correction for barometric pressure when used with a BaroTROLL device.
  • Built-in RS-485/232 Modbus, SDI-12, and 4-20mA connectivity for convenient interfacing with external devices and telemetry systems.
  • Halogen-free cables are LSZH-rated to produce no toxic fumes in the event of a fire.
  • Built-in battery and memory gauges keep you updated on the status of your unit at all times.
  • Suitable for research and testing at temperatures between -20 and 80˚C

Applications

The LevelTROLL 500 is suitable for use in almost any application where accurate monitoring of water level and temperature is needed. For situations where a stainless steel logger can safely be deployed — such as aquaculture and lake and reservoir monitoring — the more economical 400-level instrument may be an acceptable alternative.

Upgrading to the LevelTROLL 700 gives you a number of exclusive features including expanded memory, faster sampling time (up to 4 samples/sec.) and additional logging modes. Because of this, the 700 is better suited to applications where highly precise monitoring or sophisticated logging is required, including multi-step aquifer testing, earthquake detection and wave modeling.
