The Air Flow Monitor (AFM) uses ultrasonic technology to measure air velocity. The unit consists of a single transmitter and four receivers.  Air velocity and direction are calculated from measurements of the phase shifts from the ultrasonic signals at the receivers. The sensor is compact, contains no moving parts and requires no routine maintenance.  It is unaffected by interruptions from passing vehicles and acoustic reflections within the tunnel. The Air Flow Monitor is designed as a stand-alone sensor.
