Using proven, ultrasound time of flight technology ensures the AIRFLOW MkII provides consistent and accurate measurements. The data provided by the AIRFLOW-MkII can be used as part of an air quality management system within a tunnel or other confined spaces including rail and cable tunnels and mining applications.

The AIRFLOW-MkII has no moving parts and no regular service requirements, making it a truly fit and forget monitor. With industry standard SCADA / PLC interface options, such as Current Outputs, Digital Relays and RS485 (Modbus RTU) the AIRFLOW-MkII is a self-contained, intelligent, tunnel airflow monitor.
