I am trying to determine the best way to detect air flow across a cylinder in a non-invasive way. Here are the parameters: The cylinder is composed of human tissue. It's not necessary to quantify flow, only to detect its presence or absence. I'm wondering if a design using two ultrasonic transducers measuring signal differences under those two states is the best option. Another constraint is that I would like for this sensor to be no bigger than 2x3 in., and the cylinder is 1-2 inches in diameter, but it is variable.
I would really appreciate any input you can provide. Is ultrasound the best way to go? What would be the best frequency?
