Compact, accurate, efficient, robust, and easy-to-use SDI-12 bubbler
sensor for water level monitoring.
Users' Benefits:
- Accurate—Meets and exceeds USGS guidelines for water level
accuracy, and will not drift over time
- Complete Solution—Combining the CBS with an EPS-50 bubble
chamber reduces the influence of wave action and prevents unnecessary
noise in your data
- Low Maintenance—No desiccant required; 5 year life expected
based on 1 minute intervals—no pump maintenance or lubrication
required
- Easy-to-Start/Easy-to-Install—All programming can be completed
using DIP switches; connect into existing platforms using 3/8"
O.D. or 4mm O.D. measuring tube (no adapters required)
- Compact Size—Optimization of air volume required for measurement
allows utilization of a small, but powerful spur gear
motor that fits into a compact package—no compressed gas tank is
required
- Low Power—Intelligent pumping strategy compares the previous
measurement to the actual pressure at the current measurement, and optimizes
the pumping time depending on the difference (i.e., small
changes in level are measured with very short pump cycles)
Additional Features:
- Manual purge button easily accessed from the face of the unit, or
purge function available via SDI-12 command
- SDI-12 or 4-20 mA Output
- Compatible with 12V or 24V applications
- Overload protection powers the unit off if pressure or current is
too high
- No offset calibration required
- All calibration data is stored on the pressure cell so field replacement
is easily accomplished
