The TunnelTech 305 Air Flow Monitor, is an essential part of any road or rail tunnel safety system. Firstly, it monitors the airflow 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 have 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.
Fully configurable analogue and alarm outputs are provided. An RS485 link can be utilised to deliver via MODBUS protocol to a SCADA system located in the tunnel control centre.
