The discharge measurement is performed by using the proven tracer-dilution method. It can be deployed in turbulent rivers, creeks or waters for which data regarding the cross-section profile are not available.

As a tracer material salt is used. After insertion of a known amount of tracer material two conductivity probes are determining the discharge.

  • Simple, mobile discharge measurement
  • Reliable results even without knowledge and independent of the cross-section profile
  • Suitable for fast-flowing, turbulent waters or where access is limited
  • Environmentally friendly, harmless for water
  • Discharge values immediately available
  •  Easy transmission of measurement data from the sensor to receiving device via Bluetooth
  •  Convenient receiving of data on laptop
  •  Real-time visualisation of measurement data
