Cross Correlation Method

  • The measurement method for universal use in slight to heavily polluted water
  • Very high accuracy
  • Measures the real flow velocity profile

Reflectors within the water are scanned by ultrasonic impulse and subsequently are saved as echo patterns. A second scan follows a few milliseconds later.
Correlating both signals allow us to calculate the flow velocity.
Repeating this procedure in varying flow levels enables determination of the real flow velocity profile.

Corodex

Doppler Method

  • For measurement in slight to heavily polluted water
  • Latest intelligent fourth-generation Doppler technology

The Doppler method uses a continuous ultrasonic signal with a defined frequency and known angle to be sent into the water. The moving particles generate a frequency shift which is proportional to the flow velocity of particles.
These values are used for statistical averaging.

Corodex

Transit Time Method

  • For clean to slightly polluted water
  • Very high measurement accuracy

It is based on detecting the transit time of ultrasonic signals between two sensors. The signal transit time towards flow direction is shorter than against the flow direction. The difference between both transit is proportional to average flow velocity along the measurement path.

Corodex

Radar Method

  • Non-contact measurement
  • For all liquid media
  • Installation without interrupting processes

The radar merter detects the flow velocity on the water surface. The surface velocity can be detected by reflections of the radar signals on surface waves.
The evaluation of the signals are done by the Doppler method.
