Meets and exceeds USGS guidelines for water level accuracy, and will not drift over time.
Combining the CBS with an EPS-50 bubble chamber reduces the influence of wave action and prevents unnecessary noise in your data.
No desiccant, pump maintenance, or lubrication required.
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).
Small and powerful pump motor generates the required volume of air to perform measurement.
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).
