Accutron instruments the leader in ultrasonic airflow technology providing highly accurate measurements for velocity, direction and volume of air movement for demanding applications.

Use FlowTRAX as part of an air quality management system for ventilation control in road tunnels etc. FlowTRAX gives you access to primary and auxiliary fan airflow as well as drift and tunnel airflow monitoring.


  • Robust, rugged, and non-corrosive design (not affected by temperature, humidity, pressure or dust)
  • Simple installation – easy configuration and quick installation reduce project costs and start-up times
  • Maintenance free – no moving parts and virtually no calibration
  • Accurate, bi-directional readings, cross-sectional velocity averaging measurements, predominant to single point measurement
  • Reliable, designed to perform in extreme noise and hi-velocity applications
  • Versatile, pre-programmed with multiple configuration and application options
  • Built-in laser pointer for easy sensor alignment and installation
