The pandemic has ushered in a new awareness of the impact air flow might have on viral transmission. Streamwise, one of our customers, has developed an air flow probe, the ProCap low-speed flow probe, that can help users understand and optimize low-speed air flows. ProCap now comes with a three component ultrasound flow probe. With that you can also measure flow velocities in the range of 1 m/s and below. Moreover, additional quantities like speed of sound, local temperature and humidity can be obtained at the same time. A great example of innovation at work.
