Tunnel Single Point Air Flow Monitors

Compact, Precision Ultrasonic Flow Tracking

To operate massive tunnel ventilation fans with optimal energy efficiency, operators must precisely track air velocity and direction. Single point monitors, such as the TunnelTech 305, utilize highly accurate ultrasonic time-of-flight technology to measure localized air flow (-40 to +40 m/s) and temperature. Constructed from rugged 316L stainless steel and carrying IP67/IP69K protection ratings, these compact sensors feature absolutely no moving components, ensuring they remain entirely uninterrupted by traffic flow, acoustics, and reflections.
