VTT and Fläkt Woods have developed an intelligent flow sensor for demand-controlled ventilation

High quality indoor air, energy efficientlyVTT Technical Research Centre of Finland and Fläkt Woods Oy have developed a flow sensor which enables ventilation to adapt to actual demand, thereby improving indoor air quality and energy efficiency. The flow control utilises a flow sensor, based on ultrasound, which is ideal for use in challenging hospital conditions and schools, for example.Existing ventilation systems are based on estimated average occupancy rates and cannot adapt to unexpected changes in them. For example, the air can be poor in a meeting room due to inadequate ventilation,
