They work by measuring the time it takes for an ultrasonic audio pulse to be reflected the receiver across a known distance. Wind direction can be calculated by taking velocity readings from two ...

He discovered a paper from 2015 that describes the method that measures the change in time-of-flight of an ultrasonic pulse across a moving stream of air in a duct. It’s another one of those ...

Additionally, an ultrasonic pulse velocity test is planned across the entire underground network to detect damp or weak spots and prevent future accidents. Preliminary findings suggest that a ...

The radar sensors are among the most cost-effective industrial radar products on the market, needing significantly less operating power than other radar sensors. The sensors operate reliably in a -40C ...
