Introducing the NEW Level TROLL® 300... Simple, Powerful, Easy water level monitoring.
The Level TROLL® 300 is an absolute (non-vented) instrument for monitoring and recording changes in water level, pressure and temperature. The Level TROLL® 300 eliminate problems commonly found in the industry while also providing the accuracy, reliability and ease of use needed for long-term water level monitoring. Its 20.8mm (0.82”) diameter 316L stainless steel housing allow the instrument to be confidently deployed in a 25mm (1”) well. Enhanced electronic and sensor design provide long-term accuracy with internal memory of 50,000 data points and options of internal or external power allowing deployment for years. The new Twist-Lock connector eliminates worries of lost data and or communication failure while procedural and data errors are reduced through easy to use Windows®-based software. The Level TROLL® 300 provides the confidence needed to perform highly accurate water level studies with a complete and integrated solution.
The Level TROLL® 300 system is of primary interest to those who deploy instrumentation for the monitoring and recording of long-term water level changes in either monitoring wells or in open surface water. The Level TROLL® 300 instrument comes standard with the ability to communicate via Modbus, 4-20mA, SDI-12 and RS-485/232. Pressure sensor accuracy has been verified to meet or exceed 0.1% of full-scale operation, while maintaining one of the smallest sensor diameters in the industry. The new instrument incorporates a fully sealed power cell, warranted to operate for a minimum of 5 years or 1,000,000 readings, whichever comes first, eliminating worry of system flooding while also giving confidence in long-term deployment. Long-term deployment is further assured with optional external power accessories. The Level TROLL® 300 can be deployed with either suspension wire or direct read cable using the In-Situ® Twist-Lock connector. The system was extensively tested to provide sure attachment to the communication and deployment cable, thus eliminating worry of communication failure or error. Additionally, an optional external barometer (BaroTROLL®) is available for use with the Level TROLL® 300 , with seamless integration of barometric pressure compensation performed through In-Situ®’s new Baro Merge™ software.

Features & Benefits:
- Rugged, 316L Stainless Steel – Perfect for Long-term well monitoring, Dewatering, Lake and Reservoir monitoring, Aquaculture, Agriculture, and Landfill monitoring.
- Accurate Stainless Steel Sensors – Stainless Steel sensors reduce the potential for drift, which is inherent to ceramic sensors.
- TIG-welded seals – Prevents flooding of instrument.
- Ultra-low power system guarantees 5 years or 1-million readings – 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 – SCADA ready - provides for easy connections to existing and online systems
- Twist-Lock connectors that “lock” tight – 100% reliability
- Can be used with suspension wire – More economical than direct read cable
- Can be used with In-Situ®’s new Twist-Lock cables – Save time and money by downloading data from the top of the well.
- Extend cables by simply adding additional segments – maximizes your investment and maintain flexibility with your unit.
- Easiest ever Win-Situ® software – get the data you need fast! Large display that’s easy to see from a distance
- Linear logging – perfect for long-term monitoring
- Fast Linear logging – perfect for specialized tests
- Event Test Logging 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 to a different format.
- Easy-to-read memory and battery gauges – know exactly how much power is left
- Submersible pressure ranges up to 210m / 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
- Model number, serial number, pressure range and manufacturing information printed on side of the unit – know the details of the unit without opening the software. Reduces accidental over pressuring
