| Features
- HOBOware™ software provides easy conversion
to accurate water level readings, fully compensated for barometric
pressure, temperature and water density
- Use either a second water level logger or
a HOBO Weather Station for barometric compensation when needed
(one barometric data set can be used with all water level loggers
in that area)
- HOBOware provides comprehensive graphing,
analysis and reporting
- No-vent-tube design eliminates installation/maintenance
issues and errors associated with vent tubes, such as bulkiness,
desiccant maintenance, water in tubes, cuts, and decontamination
between deployments.
- Fully sealed housing insures many years of
trouble-free operation
- Optical/USB interface for years of reliable
data offload in wet environments—no mechanical or elastomer
connectors to fail
- Streamlined housing for snag-free deployment
in wells
- Lightning protection—no long signal
wires, and electronics are shielded in stainless steel housing
- Durable ceramic pressure sensor
- Simple wireline mounting makes it easy to
hang logger in wells, hidden from vandals
- Multiple-rate sampling allows faster sampling
at critical times such as when pumping starts or stops
- Includes calibration certificate of accuracy
versus NIST-traceable standards at three pressure points (15,
21 and 29 psia)
- Patented technology (U.S. Patent 6,826,664)
Key
Specifications
Water Level Measurement
• Range: 9 m (30 ft); 0-207 kPa
(0-30 psia)
• Factory Calibrated Range 69 to 207 kPa (10 to 30 psia);
0° to 40°C (32° to 104°F)
• Typical Accuracy: ±2.1cm (0.07 ft); <0.1% of
full-scale pressure over full temperature and pressure calibrated
range
• Resolution: 0.21 cm (0.007 ft); <better than 0.01% full-scale
pressure
• Burst Pressure: 310 kPa (45 psia); 18 m (60 ft) depth
Note: all depth specifications assume use in
water at sea level.
Temperature Measurement
• Range: -20° to 50°C (-4°
to 122°F)
• Accuracy ±0.37°C at 20°C (0.67°F at
68°F); ±0.5°C (0.9°F) over -5° to 50°C
(23° to 122°F)
• Resolution: 0.1°C @ 20°C (0.18°F at 68°F);
10-bit; 0.2°C (0.36°F) over -5° to 50°C (23°
to 122°F)
• Response Time: 3.5 minutes in water, typical to 90%
• Stability (Drift) ≤0.1°C/year (0.18°F/year)
Optic
USB Base Station
 An
Optic USB Base Station is required for communications between the
HOBO Water Level Logger and a PC. Simply plug the Optic Base Station
into a USB port on the PC and the Water Level Logger into the Optic
Base Station.
• Optic USB Base Station offloads full logger in less than
30 seconds
• Optical interface to logger eliminates unreliable connectors
• Easy USB connection to PC
• Operating Range: 0° to 50°C (32° to 122°F);
0 to 95% RH, non-condensing, non-fogging
Required
Software
HOBOware™ for Windows®
software is required to operate the HOBO®
U12-015 logger. Each starter kit includes software, USB interface
cable, and software manual. |
