Flow Trax


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.

Our team works closely with Mining and Industrial Electrics (MIE) and Accutron Instruments to curate custom solutions for underground mining applications. From mine ventilation to gas detection panels, we work together with our customers to ensure they comply with regulations and meet mine site requirements.
