CROSSFLOW

The CROSSFLOW tunnel monitor uses proven ultrasound technology to measure the speed and direction of air movement within multi-lane and bidirectional tunnels. These measurements can be used as part of an air quality management system for ventilation control within a road, rail or mining tunnel.

FEATURES

  • Proven ultrasonic transit time measurement technology
  • Measurement independent of temperature, pressure and composition of the tunnel atmosphere
  • Pre-calibrated “Fit and Forget” sensor with fixed ultrasonic path length
  • Single and dual axis mode available
  • Intelligent analyser with optional TSCU operator interface
  • Choice of interface options enabling easy integration into tunnel control system
  • CROSSFLOW-T model with integrated temperature sensor

BENEFITS

  • Designed specifically for in-situ monitoring in tunnels
  • Rugged design to withstand corrosive atmosphere and regular tunnel washing
  • Prewired interconnecting cable and termination points saves time during the installation
  • No moving parts and low maintenance requirements
