Accurate, real-time airflow monitoring systems designed for mine ventilation optimization.


FLOWTRAX

Ultrasonic Airflow Monitor

flowtrax-large


The leader in ultrasonic airflow technology providing highly accurate measurements for velocity, direction and volume of air movement in demanding mining environments.

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

Features

  • Ultrasonic time of flight technology in real-time with continuous monitoring
  • Digital signal processing, Modbus RTU and analog 4-20 mA output
  • Advance detection of false readings and sensor obstructions caused by moving vehicles and personnel
  • Robust design capable of operating under extreme temperature and harsh industrial environments
