The CS470 is a compact bubbler that generally measures ground or surface water level, but can also measure any liquid level. This bubbler has an accuracy of ±0.02 ft. A Campbell Scientific datalogger controls the CS470's pump and calculates the measurements. The bubbler typically communicates with the datalogger via the SDI-12 protocol. Many of our dataloggers support SDI-12.

Benefits and Features

  • Ideal for areas where submersed sensors can be damaged due to corrosion, contamination, flood-related debris, lightning, or vandalism
  • Compatible with most Campbell Scientific dataloggers
  • Easy to maintain
  • Robust pump design provides reliable operation
  • Consistent accuracy ensured by drift-free measurements and offset compensation using relative measurement
  • Purge function clears the measuring tube and the bubble chamber of contamination
  • Does not use pressurized nitrogen tank—requiring less frequent attendence
  • Existing tubes can be used
