Constant Temperature Anemometry (CTA)

If you’re looking for a technique to measure the turbulence in gas and liquid flows, Constant Temperature Anemometry (CTA) is the answer. CTA, also known as Thermal Anemometry, Hot-wire, or Hot-film Anemometry, uses hot-wire or hot-film probes inserted into the flow to measure the turbulence.

It’s an ideal method for measuring flows with fast fluctuations at a point (high turbulence) and studying flow microstructures. It’s capable of resolving small flow eddies down to the order of tenths of a millimeter.

Key Benefits

  • Covers a wide range of applications
  • Ideal for studying turbulence
  • For fine-scale turbulence and boundary layer measurements
  • Turbulence spectra can be resolved in >4 decades of amplitude
  • Provides the full velocity vector
  • Straightforward analysis of data

Key Features

  • Measures velocities from a few cm/s to supersonic
  • High spatial resolution: eddies down to 1 mm or less
  • High temporal resolution: fluctuations up to several hundred kHz
  • Low noise level
  • Continuous analog output

Choose CTA, and you’ll get the precise measurement you need.
