TBU360 - TCU Bubbler Unit

TCU Telemetry Control Unit - TCU001 all-in-one pump controller

TCU Bubbler Unit
Compact, patented design allows bubbler transducer unit to be mounted in the control panel - instead of the wet well!

The TCU Bubbler Unit (TBU360) is a low-cost well-level solution based on the KISS principle. It has a small, compact design that allows the bubbler transducer unit to be mounted in a control panel – instead of the wet well.

  • Patented design with footprint that is less than 10% of a typical bubbler system
  • Dramatically outlasts submersible pressure transducers
  • Does away with float cables, mercury switches and differential pressure settings
  • No more air compressor, air tank, or flow regulator to adjust or maintain
  • No voltage signals introduced into wet well
  • Non-clogging, self-cleaning
  • Detects air-pump failure without the use of flow switches
  • Small compact air pump (3.25" width x 4.25" length x 2.75" height)
  • Supports both continuous draw down (pump down) and fill up (pump up) operation
  • Can be programmed for incremental level readings similar to floats
  • Transducer is powered by the Telemetry Control Unit (TCU)
  • Repair and replacement parts available separately
  • Full one year warranty on parts


Eliminates need for big, expensive air compressor, tank, flow regulator, mercury switches, and differential pressure settings.

This level sensing and fault detection device is an optional add-on to Data Flow Systems' popular multi-pump controller, the Telemetry Control Unit. The TCU analyzes a 4-20 mA signal from a pressure transducer to detect well level and proper operation of the bubbler's air pump.

If you already have a TCU, you can integrate the bubbler system into your existing system. (The TCU must be running the TCU90000 program version 2.6102411 or later.)
