The OTT Compact Bubbler System (CBS) is a lightweight water level bubble gauge, design to measure water levels accurately for up to 30m.
Different to common water level meters, a Compact Bubbler System operates on a highly accurate drift-free air bubble principle. This technology utilizes a small piston pump to compress air through a measuring tube and bubble chamber into a water column. By comparing barometric pressure to the bubble pressure, the Compact Bubbler System calculates water level height.
Due to the indirect measurement principle, and with no electronic parts in the water, Compact Bubbler Systems are particularly suitable for monitoring areas prone to lightning strikes.
Three Compact Bubbler System models are available:
• OTT Compact Bubbler System (15m / ± 5mm accuracy)
• OTT Compact Bubbler System (30m / ± 5mm accuracy)
• OTT Compact Bubbler System USGS (15m / ± 3 – 5mm accuracy)
CBS Data Output
The OTT Compact Bubbler System is capable of outputting water level data as:
• 4/20 mA
The OTT Compact Bubbler System can be configured either output mode by configuring the 8 DIP switches located on the underside of the device.
Outputted units of measurement include:
• Meters (m)
• Centimeters (cm)
• Feet (ft)
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).
