300 Series – 301 Airflow Monitor

The TunnelTech 301 Air Flow Monitor (AFM) is CODEL’s industry proven tunnel air flow monitor.
Tunnel ventilation systems are designed to enable a sufficient throughput of air to be maintained to ensure a safe operating environment for users. These systems consume large amounts of power and need to be operated as efficiently as possible. To do this it is necessary to know the effectiveness of the system in terms of air flow and direction developed within the tunnel.
Three decades of development, knowledge and practical experience have been utilised to produce the advanced TunnelTech 301 air flow sensor that combines the reliability of ultrasonic technology  and delivers superb accuracy and reliability at a very competitive price.
