Ultrasonic anemometer “point type” UFM5

The UFM5 ultrasonic air flow meter is an innovative device that revolutionizes the way we measure air velocity and direction in tunnels; Unlike its counterpart, the tx+rx type (UFM20), the UFM5 features an uncomplicated installation, using a point transducer placed directly on the tunnel surface; This little technological marvel is responsible for accurately measuring the average air velocity and direction in the tunnel section, providing crucial data for efficient airflow management;

What makes the UFM5 exceptional is its simplicity and accessibility; Its installation is so simple that it does not require complicated alignments or cumbersome configurations; Once in place, it is ready to operate immediately, providing accurate information without any additional effort on the part of the user;

In addition to its ease of use, the UFM5 is extremely versatile; Not only is it ideal for measuring the natural air flow in the tunnel, but it can also be used to adjust this flow with intelligent ventilation control; If the gas level or air opacity exceeds certain limits, the UFM5 detects these hazardous conditions and sends signals to the tunnel ventilation control system; This allows a fast and efficient response to clean the air, ensuring the safety of those passing through the tunnel and, at the same time, saving energy in an optimal way;

The operation of the UFM5 is based on a precise interaction between a defined sound path and the wind; Air modifies the time and manner of sound propagation, resulting in reliable and accurate measurements; This innovative system is not only an indispensable tool for airflow management in road tunnels, but also finds valuable applications in various situations where detailed air monitoring is required;

In short, the UFM5 not only simplifies airflow measurement, but also sets a completely new standard for accuracy, reliability and ease of use; With its state-of-the-art technology, this device has become the preferred choice for engineers and professionals seeking an effective and efficient solution for air monitoring in tunnels and beyond;
