Hi all. I would like to ask, if I should be worried about interference from the walls when I will use ultrasonic sensor inside closed metal (relatively) small tubular container. (To measure height of stuff inside.) Alternatively, is there any better contactless way I can use? Thanks, Libor

Ultrasonic sensor interference with walls

The cone of the sound is determined by physics, not much you can do about that. Same for light.
