Its ultrasonic sensors provide reliable measurement across the tunnel profile for tunnel ventilation control systems. Two identical sensors alternately transmit and receive ultrasonic pulses. The system evaluates the transition times dependent on direction and calculates flow speed. Key Benefits Extremely low maintenance Reliable [&hellip;]"}
