VELOCIMETER

Vectrino Profiler

Boundary velocity profile measurements over 30 mm with 1 mm vertical resolution

Highlights

  • Boundary profile measurements
  • 1 mm vertical resolution
  • 100 Hz maximum sampling rate

Overview

  • As the name suggests, this velocimeter is the profiling version of the Vectrino system. The Vectrino Profiler’s strength lies in collecting a small profile of up to 30 cells that are only 1 mm in height. It is globally used as the standard flow-measuring tool for hydraulic laboratory applications.

Applications

  • Projects highlighting the effect of vegetation on near-bed flows
  • Simulated bed changes in flumes
  • Measurements of high-resolution flow profiles in laboratory flumes
  • Turbulence measurements in laboratory flumes
