Hi All


Is it possible to make a range meter with ultrasonic sound, which can measure over 15 meter, maybe 100?

Through water yes, but in air , well.. it would take an ear splitting amount of sound, lower frequency waves may work better.

Commercial units measure up to 30 meters, so it should not be too dificult. If you use a parabolic reflector at the target and source, it should be easy.
