The OTT CBS is a compact, accurate, and low power bubbler sensor for surface water level monitoring. The OTT CBS meets or exceeds USGS standards for accuracy, and will not drift over time. It features outputs for SDI-12 and 4…20 mA.
Surface water, Groundwater
Drift-free water level measurement – no pressure sensor or electronics in the water
0 to 15 m or 0 to 30 m
± 3 mm (high accuracy version); ± 5 mm (standard and 30 meter versions)
SDI-12, RS-485 (using SDI-12), or 4 …20 mA
Examples of Use
For water level measurement of:
Streams, rivers, channels, or canals
Reservoirs, lakes, and wetlands
Ideal for monitoring:
Continuous water level networks
Lightning prone areas
Channels with long, flat embankments
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, pump maintenance, or lubrication required
Easy-to-Start/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—small and powerful pump motor generates the required volume of air to perform measurement.
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)
