Levelogger Series Model 3001 Data Sheet Levelogger® Low-niaintenance Model 3001 factory sealed design The LT Levelogger is unique in that the datalogger,battery, pressure transducer and temperature sensor are all housed in a very small, minimal maintenance, 7/8" x 4.9" case. Datalogger The sealed design offers protection against power surges 10 year battery such as nearby pumps or lightning, and greatly simplifies ,.r maintenance. Leveloggers offer superior flexibility compared to other water level dataloggers. They can be suspended on a simple wireline, or connected to the surface with direct read cable for simple downloading of data and/or reprogramming without removal frorn the water. Use of the wireline further Pressure transducer reduces costs and allows the Leveloggers to be totally hidden Temperature sensor frorn view and locked away from possible damage. A 10-year battery life, high accuracy and.long-term stability all help to make Leveloggers the ideal device for recording Better than Ever water levels in monitoring and production wells,boreholes, Accurate, Reliable and Easy lakes, rivers, tanks, harbours, etc. • Smaller than ever: 7/8"x 4.9" (22 x 125 rnm) Leveloggers are available in a variety of ranges, in the three • 0.1%FS accuracy and long-term stability models described below. • Lower price The fully automatic, easily programmed Levelogger allows • Logarithmic, event-based or linear sampling measurements at selected time intervals as small as 0.5 sec. with no wraparound, so that it does not overwrite data. Infra-Red Data Transfer ' Logarithmic and event-based sampling regimes are also • No vented cable or desiccant problems easily programmed in the easy-to-use software. - 2-conductor cable or simple wireline • Protected from power surges (pumps, lightning) • Maintenance-free, water-tight Very Friendly Software • Easy data export to spreadsheets and databases • Automatic temperature compensation zr yr • Barometric compensation wizard Barometric Applications Telemetry ► Pumping and slug tests Telemetry systems are available for Leveloggers.
