Water Level Sensors

CBS

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.

CBS Models

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:

• SDI-12
• 4/20 mA
• RS-485

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)
• MBar
• PSI
