FloStick RC4

The Integrated Electromagnetic Velocimeter

The FloStick electromagnetic velocimeter (or current meter) is a portable and economical device for measuring and recording water flow velocities.

The FloStick combines a probe, a wading rod and a display in a single unit, making it very easy to handle and allowing for very quick measurements in the field.

Simple to use and requiring no parameterization or adjustment, the FloStick is the ideal tool to obtain precise velocity measurements in a few seconds, even for low flows or low water level.


Temporary and fast measurements of velocities and flows for many applications in fresh water, salt water, wastewater, etc.:

  • Rivers and streams
  • Irrigation canals
  • Inlet canals
  • Sewerage networks
  • All open channel gauging

Main benefits

  • The measurement is not dependent on water turbidity, temperature, conductivity (except for extreme values).
  • The measurement is unaffected by turbulence, vibrations, external noise, etc.
  • Suitable for clean and wastewater
  • Can operate with low water levels and low velocities
  • Fast and accurate measurements, without the need for special analyses and processing
  • Bidirectional measurement
  • Robustness (no moving parts, no transducers, etc.)
  • Recording of measurements
  • Easy to use, with a graphic display and navigation wheel for configuration and viewing of instant and recorded measurements
