The TunnelCraft 3 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. 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 in the tunnel. Three decades of development, knowledge and practical experience have been utilised to produce this advanced technology tunnel sensor that...
