Flow measurement in open channels

Flow measurement in open channels


By associating a level measurement to velocity measurements, the flow is obtained by adding of flows in each elementary phase of heaved section.




A complete installation is made of :

  • 1 convertor
  • 1 or 2 level detector
  • 1 to 8 path to measure the speed

Installation of probes

The number and the position of probes will depend on :

  • the height of the application
  • the difference between the lowest and highest level of liquid
  • the upstream and downstream particularities on site
  • the accuracy required

Advantages and strong points

  • Nature of liquid and its temperature does not have any influence on the measurement quality
  • Process depends only on the onsite dimensions and the positionning of the probes
  • integration on the full length
  • huge range of measurement
  • can measure very low and very high speed
  • tolerate a huge level variation Flow measurement in open channels in Vernon - FRANCE
