BubbleFLO2

Communicating Bubble Flowmeter

The BubbleFLO2 bubble flowmeter is designed for level measurements and flow calculation in open channels, sewage treatment plants, sewage networks...

The BubbleFLO2 integrates its own air generator; it is unique due to its ability to communicate over a cellular network and to add external sensors, such as the DVP Doppler sensor, rain gauges or physico-chemical sensors.

It is part of the Hydreka instrumentation family and can be operated by WinFluid NG and WebFluid software.

Applications

The BubbleFLO2 flowmeter is mainly used for the following applications:

  • Diagnosis of wastewater networks and natural environments
  • Self-monitoring of wastewater treatment plants
  • Control and regulatory monitoring of urban and industrial wastewater discharges in open channels
  • Any other flow measurement in difficult environment (fouling, temperature gradient, foam...)
  • Installation on weirs, gauging channels...

Main benefits

  • Minimally influenced by environmental constraints (foams, debris, turbulence, silting...)
  • Measuring cell is not in contact with the liquid
  • Possibility to add sensors on the same central unit (Doppler, physico-chemical, rain gauge, level detector...)
  • Automatic sampler control
  • Fine control of bubbling for precise monitoring of the measurement, regardless of the variation in height
  • Integrated hydraulic level to flow rating tables
  • Can be used without software, via integrated screen and keyboard
  • Can be used as a fixed station (powered) and stand-alone portable station (battery-powered).
  • Can be used with Hydreka overflow shutters, Venturi channels, Parshall channels etc.
  • Integrated cellular communication with remote reprogramming capabilities
  • Compatible with SCADA software or other platforms, including TopKapi
  • Compatible with Hydreka water data management software (WinFluid NG, WebFluid NG)
