Product Details

TSI's thermal anemometer product line offers flexibility in designing a system that meets your flow measurement needs. You can select specific components from our full line to integrate with those you may already have or you can select a complete system and expand its capabilities by adding accessories. Every system must have an anemometer; one or more single-component, two-component, or three-component probes depending on your application; and an equivalent number of probe supports. Most systems will also include a probe calibrator, A/D converter, thermal anemometry software, and a computer.

You may also choose to purchase probe calibration services from TSI.  

Features and Benefits 

  • Measures rapid changes in flow velocity
  • Wide variety of probes and geometries
  • Cost effective flow measurement methods


  • Excellent for measurements in turbulent flows
  • Measurements in restricted spaces

  • How do I know which anemometer system is best suited to my needs?
    There are two primary considerations when evaluating systems for purchase: present requirements and possible future requirements. Important questions to consider include the following: What is the velocity range (and, therefore, frequency response) I may need to characterize?   How many sensors will I need to operate simultaneously?   Do I need to measure one, two, or three dimensions of velocity?   Will there be rapid temperature fluctuations in the flow that I will need to measure?   Do I, or will I, need to use an automated traversing system to position the thermal anemometry probe during measurements?   Is the computer system that I will be using an important consideration?  The IFA300 Anemometer and its associated ThermalPro™ software can accommodate probes for one-, two-, and three-dimensional fluid measurements. Up to 16 total channels can be accommodated with the system. Due to its fast response characteristics, the IFA300 is well suited to virtually all velocity regimes. In addition, the IFA300 and ThermalPro software can incorporate specially designed Constant Current Anemometer channels for fast-response measurement of fluctuating temperatures. The IFA300 system also offers the ability to control an automated traverse system and can even control an automated air velocity calibrator.
  • What are some of the properties and parameters that can be measured using thermal anemometry?
    In addition to velocity, the following can be measured: temperature, density, concentration in binary gas mixtures, wall shear stress, vorticity, pressure, heat flux, etc. Sensors can also be used to detect boundary layer transition and flow separation.
