Tunnel Pollution Monitoring
MerseyTravel contracted AIS for the design and development of a pollution monitoring and SCADA system.
The system includes fourteen sensors in the two Mersey Tunnels that monitor levels of CO, NOx, Visibility and NO2. The data from these are sent back to a Siemens PLC that feeds information into the existing SCADA system as well as driving a new overview mimic for both tunnels.
The system involved a phased installation and transition from the existing sensors to the new sensors and from the existing SCADA system to the new SCADA system.
