TunnelTech 305 – Air Flow Monitor
The TunnelTech 305 Air Flow Monitor, is an essential part of any road or rail tunnel safety system. Firstly, it monitors the air flow measurement as well as the direction of flow inside the tunnel and ensures that the tunnel ventilation system provides sufficient clean air to protect tunnel users health and for drivers to clearly see the road ahead.
The TunnelTech 305 uses dual path ultrasonic technology to ensure high accuracy and having no moving parts, reliability levels are very high and maintenance requirements are very low. The sensor is constructed using stainless steel for ultimate protection against the harsh environments found in tunnels.
